When I first installed TSReader, it would often display thumbnails of the playable TV channels it found.  Now all I ever get in that "Video Decode" (right-hand) window is "Decoder Disabled."

How can I correct this?

This is very strange.  This happened to me with a new (old) computer I put together a few weeks ago. 

I'm curious whether what you're observing is on an existing installation that worked before, or if you installed TSR on a different NEW computer?   Or is it a new download of TSR?
   If a new computer, what hardware is involved?  Ie CPU/cores, and what kind of video card?

   In my case, my son had given me an OLD motherboard, ie an old 2CPUX2core=4 total cores motherboard with AGP slot instead of PCI-e.   I had to look around and find what I thought was a modern AGP video card, but in the end it doesn't seem to have hardware acceleration. 
   Anyway, when I installed Windows (XP-Pro SP3),  and TSREADER, I saw the same "Decoder Disabled" thing on the thumbnail pictures.  I've been using TSREADER for about a dozen years, and have never seen that before.   I just assumed that there must be some problem with the OLD hardware on this motherboard, as it's a motherboard that my son stopped using and replaced with a newer MB. 

   On the other hand, I have another computer that is much older than this one, and also has an AGP video card, and TSR works fine on it, actually better than on my newer computers.  So it's probably not the old hardware that's causing the problem.

   Anyway, I had given up on using this OLD computer for playing video, since the video card apparently doesn't have hardware acceleration, so I didn't bother trying to troubleshoot this Decoder Disabled issue, but now that I see this post about a similar problem, I'm wondering if maybe it's somehow related to new versions of TSR, because I think I put the newest build available on this computer.  Maybe I should try going back to an older version?  

    Also, I'm wondering if this motherboard having  dual  2-core processors might have something to do with it?  The reason I put this computer together with the old motherboard, was that I was curious relative to whether 2 CPUs with 4 total cores would be better than a single CPU with 4 cores.  Ie maybe the OS isn't handling the cores in the same way.  

    There is a command line option with TSR to have it run in a single core.  Perhaps TSR isn't communicating with the video decoder if it's running on a different CPU????   So I'm curious how many CPUs are in your computer???

    Anyway, I thought this was strange when I encountered it, but now that it's more than just me, it's even stranger.

what's the command line switch to use multi-threading / multiple cpus?
Haven't seen that. Not sure why tsreader would have that option as other than that thumbnail, it doesn't really do any decoding does it? Pretty much just parses what it sees and displays tables right?

Do you have the same issue if you use a 'DVB-S' source to tune instead of Crazyscan streaming to the UDP source?
(from the screenshot, I assume that's what rempfer is doing).

wejones, I believe I am using TSR on a computer that in the past did display the thumbnails, but I'm not certain.  The specs for this laptop are:
- WinXP SP3
- Lenovo Thinkpad T61
- Intel Core2 Duo 2.00 GHz
- DirectX 9.0c
- Intel Mobile 965 Express (video) Chipset
I did check dxdiag to make sure all the DiredtDraw & Direct3D acceleration features for the video chipset are enabled and I made sure that in Display Properties, Settings, Advanced, Troubleshoot that Hardware Acceleration is on Full.  

majortom, since I was streaming from EBSPro to TSReader, I did try launching TSReader directly, selecting first DVBSBDASource ("DVB-S BDA compatible source") and then BDASource_TBS5925 ("TBS 5925 Box"), but the "Decoder Disabled" condition was not resolved.

I have another computer handy, so I think I might try this same (latest) version of TSReader on that machine (running Vista) to see if it makes any difference.

Thanks for your replies.

Re command line switch, I think it's just    -1    to run in single core.   I can't remember why I used it once, but I was having a strange problem a year or two ago, and someone suggested using that switch, and it worked.  I since stopped using it, though, as I think I ran into some other issues.  But I'll have to try this to see if it affects this issue.

Re TSREADER doing decoding,  yeah it doesn't do a whole lot of decoding besides the thumbnails, other than to get info, but it does have to look at the video stream headers to get the video type info, and there is often quite a bit of decoding involved in SDT, NIT and EIT packets.  I seem to remember older versions of TSREADER only using 5% CPU back with an old single core 1.8 GHz computer with DVB-S transponders and lower bitrate channels, but I've noticed that with newer versions of TSREADER on DVB-S2 8PSK transponders that have either high bitrate MPEG4 video streams or a lot of video channels, that TSREADER can use in excess of 30% CPU on my 4 core 3.4 GHz machine, ie too much to fit in one core.  One reason I used to use that switch was to keep TSREADER in one core, and use the other 3 for VLC or whatever player I was using, but now it seems like TSREADER won't fit in a single core sometimes.   



Re DVB source vs TCP or UDP source, I can't remember.  I don't have a card on that computer right now, so maybe Rempfer can comment, but I'll put a card on there and try a few things anyway.

I just put my TeVii on the suspect computer, and called up TSREADER with the -1 switch, and locked the 12180 PBS mux on AMC21.   Still gives the Decoder Disabled message.  It's running about 16-18% CPU on this 2.8 2x2 core computer, so it fits inside the single core, and there is almost zero activity in the other cores. 
   I pulled up the same transponder on my other computer, which is the 1x4 core 3.4 GHz machine, and it's running about 13% CPU there right now, and displaying thumbnails fine.   It's running the same 2.8.47 version of TSREADER, but I think it's an older build date.  This 1x4 computer has more programs on it, so it may have some things on it that might help display thumbnails, but I can't imagine what it could be.  I tried removing a couple processes to see if I could disable something that was doing the thumbnails, but it didn't change anything.
    I'll have another look at the TSREADER settings in the registry, but I did this before, and couldn't find anything related to thumbnail display. 


EDIT:  BTW, I really can't understand why TSREADER uses so much CPU time.  I used to run TSREADER in a single core laptop running less than 1 GHz, yet on these faster machines, it seems to use a lot of CPU time now.  It actually uses more CPU than some of the playing programs use to play HD H264.

If we can determine that it's a quirk in newest release of TSReader, maybe we could let Rod know to see if he'd fix it.  The thumbnails are a handy feature.  I am downloading the previous (b) version now, to see if that version will display the pics.  wejones, what version specifically are you having success with?  I'd like to (see if I can) reproduce your experience here.

I think it's a time-out issue when TSR is loading the thumbnails (or trying to)

when I look again at my snapshot I notice the 1st two thumbnails are h.264 and the next two are mpeg, maybe it's an h.264 problem?

EDIT:
when comparing with the O.P. (rempfer) snapshot I notice all of his are no pics, just test cards, and the crashed ones on mine are test cards, while the actual video comes in?

yeah, crashed and disabled are different issues I would think.

Well, I got it to work.  And I feel dumb. 

It looks like the new version of TSREADER has default values of zero filled into the options in the Refresh rate/maximum pictures window.  When I filled realistic values there, everything works.  Try 20 in all 4 windows.


BTW, it was voomvoom's comment about timeout that made me think of that.

I got it to work just by dumb luck.  I uninstalled TSReader2.8.47c and installed TSReader2.8.47b.  The thumbnails displayed okay in that previous version. Then I uninstalled b and reinstalled c and the thumbnails started working in this latest version.

So, when I came back here to post these results I saw wejones's most recent post.  Egad.  So with the thumbnails now working through dumb luck, I checked out those options and set the now-visible thumbs to refresh every 10 seconds.

Too cool.  Thanks to everyone for their help.  Sometimes doing things the hard way actually works!

Life is good.

I reset mine to 20 and haven't seen a crash since.

After reading your post just now, I've reset mine to 10.

BTW, I sometimes have problems if I set that refresh rate too low, if there are a lot of channels in the mux.  Seems like then it doesn't have time to print out all the images.

Re those maximum pictures numbers, sometimes I would see thumbnails that only had partial pictures.  Turned out that the transponders weren't sending the complete frame each time.  But if you increased that number to around 30, then the whole picture would print out, because it would collect more partial images.  However usually 10 or so would work fine.
