Thought that this program had lots of potential. I have used it with difficulty.
Now, my malware program finds a "Trojan bug" embedded in the software attributed to a gen-pix driver. When Windows Malware gets rid of it, SmartDVB tries to install itself again and the Bug returns.

Anyone else share this problem?

No,  but you often have to try more aggressive means to get rid of a trojan.
Try submitting it online for a thorough test scan  http://virusscan.jotti.org/en and that will at least tell you what it is.  You can google how to get rid of it,  if you don't have a AV that will heal it or quarantine it.  I've had to resort to that dreaded reinstall several times.

I was not able to upload the file. Message, "I do not have permission from the owner of the file".

Best thing to do is to get rid of the program.

Hello,

I'm the author of SmartDVB. The genpix.dev was provided directly by genpix and seems to be packed with a program which results in an false positive on some virus software. There's absolutely no virus in there. And if you don't use a genpix device it can simply be removed without affecting the program. You can also download the latest genpix.dev (0.0.5) from here on the genpix site. Next version will also have support for the recently released genpix bda driver.

Btw, what were the issues you had with the program? I'm based in europe so the only way for me to improve NA support is by feedback i get from you guys.

Hello Jack:

Using Windows 7 and Microsoft Malware software. It seems that the moment that I make a change in the SmartDVB folder The application re-installs itself and genpix.dev appears again. It all began when I downloaded the latest BDA.dev. A message comes on saying: to wait while windows configures SmartDVB. SmartDVB starts and genpix.dev appears in the device folder.

Glad to see you on this board.

Hi,

This seems odd but i'm no expert on windows 7. But i can assure it's not something that's internal to smartdvb so must be something win7 does when it detects removed files from the application path. Just to check i reinstalled smart here on my win7 system and indeed when removing genpix.dev and restarting smart i removed bdas.dev (genpix.dev was detected on install my mcafee and removed automatically) and the system reconfigured itself and installed bdas.dev again. Funny didn't know that..

Just recently found this board. Happy to be here.

I am glad to know that I am not loosing it (yet).

I know that you have put a lot of work into SmartDVB. Anything we can, just ask the members here.

This is what I did I had windows malware remove the genpix.dev file, then I opened notepad and saved a blank file as genpix.dev on the devices folder.

next time I opened SmartDVB it did not reconfigured itself. Good News.

Now I will try to use the new BDA device and see how it plays.

Good night

Btw, what were the issues you had with the program? I'm based in europe so the only way for me to improve NA support is by feedback i get from you guys.

Saw this and figured I'd try it too.
First thing I tried was to tune Local Broadcast ATSC Signals, using an EVGA inDtube ATSC Tuner (a USB BDA dev, running WIN7).
I haven't spent a whole lot of time with it yet, but so far I can't get it to obtain a lock, it shows up as eMPIA Technology USB 2883 Device.
Made sure the ATSC "transponders" were set for 8VSB Modulation.
is it possible we need to play around with the frequencies to match the North American Broadcast Freqs? SR for NA ATSC should be 19280 but I don't see any setting for that. Is it hardcoded as 19280?

Also tried the Prof 7500, and haven't got that to lock known good sat transponders yet either (pretty sure I had the LNB setup correctly for that).
Like I said, haven't spent a whole of time with it yet, if I get anywhere with it I'll post any observations.

@majortom: atsc support isn't working, never got anyone to test that and isn't included in the bda.dev yet (there was some code for it in the old bdas.dev though but never got any feedback that it worked). If anyone is willing to work with me i'll add it to the current bda.dev device these days.

Prof7500 has been reported to work (as other prof and tbs devices), at least with the older bdas.dev (you could try that also to make sure) so i'm quite sure it should tune so might be diseqc config perhaps.

Also for prof7500 make sure the device setting is set to the specified card, might be that the current driver you downloaded doesn't autodetect every card correctly. (you could look into the bda.log for that)

hi jackjavo,

Consider this as feedback that ATSC does in fact seem to work. It's almost there
now as is anyway.
If your willing to write the code, I'd be more than happy to help ya test anything ya come up with. BTW,  I was right in my suspicion that the ATSC Frequencies were just off a little bit.
If I subtract 2 Mhz from the frequencies as listed in 4000.ini, I can get my ATSC tuner to lock, and it scans in channels. So that's good. I can get video to graph also, but so
far having played with AC-Filter, and ffdshow as the audio filter, I can't get any audio yet. But I'll keep playin.
ATSC in NA uses AC3 audio (A52 in the standard).

Another observation is that in ATSC there's an extra table that your apparently not reading. It's the Terrestrial Virtual Channel Table (TVCT). That's where they put the information regarding the Station description. Say 7.1 WABC-HD for instance.
By reading the PMT only, every channel just scans in as Noname - SIDx. The SID info isn't really used for anything in NA Terrestrial Broadcast.

I can collect some .TS Logs for every station in my area here if you'd like to play em back in TsReader or something. Just let me know.

More detailed info of the ATSC standards are found here:
U can download them all for free.


and here's a handy one for quickly looking up specific fields, etc..


and here's a couple example TsReader HTML exports from a couple local stations around here:



PS - I'll get around to playin with the Prof 7500 too over the weekend and provide some more feedback.

Okay thanks majortom for this useful feedback,

I did some research on atsc earlier today and indeed figured out i will need to parse vct as u mention. Also i see the ac3 used is the same as eac3 which i just recently added to the current build. You might be able to select the audio PID in the channel properties and simply mark it as ac3 by editing it, this would send it as ac3 to the audio decoder. Another sat user got ac3+ to work this way as a workaround.
I also see there are various qam specific atsc tuners also so will have to look how to integrate that also and it also seems that scans can be done  by simply specifying the physical channel (on non qam atsc), this would prevent any ini frequencies confusion. And lateron i can simply add the specified frequency from the vct to the channel. Is all doable but a bit more work than i anticipated lol, thought it was simply a matter of getting the bda tuning correct. And i also see eit information is also very different so atsc epg is another thing entirely too it seems.

Thanks i'd appreciate any dumps indeed, i can run them in debug mode to test.

jack, 
Ha, got the AC3 audio working. After flipping thru some more filter combinations, audio renderer, etc. I found one that works. I think it was the Audio render setting that did it. Audio on all channels now too. Nice work. 

I'll work on some .TS logs as soon as I get a chance. I'll post em as public Google Docs links (public for all with link) if that works for you....

i downloaded this program too. very nice video and audio ( since i too found an audio renderer to work ). only problem i'm having is setting up the 4x1 diseqc switch so i can scan in the Ku channels. so far i have G16 scanned in.

which diseqc setting should be used for the 4 way switch? i have c band on diseqc 1 and Ku on disecq 4?
so far i like the program,now if i can get the hang of navigating thru it and learning the settings.
