Can't tune certain channels with HDTV card

[tomas.z]

I have ATI HDTV Wonder and in WatchHDTV program I can watch following four channels(info from http://www.remotecentral.com/hdtv):

channel-sub channel-psip channel number
20-1-5
40-1-9
66-1-52
53-1-57

With GBPVR, when I switch to channels 40 or 66 (second and third in above list) I get black sreen and no sound. The signal meter shows full quality and high strength (but it does not seems to be moving at all on those channels).
The attached jpg shows what is in my tuning for the channels.
I wanted to attach a log file as well but I'm not sure which one.

Any advice and/or help would be greatly appreciated and I can also do some testing if needed.

Thanks.

Zip and attach a complete set of logs and I'll take a look.

Here are two sets of logs.
The first one(logs_original.zip) is zip of all the logs that were present after installing, configuring and using the application.
The second one(logs_aftercleanup.zip) contains logs after deleting all existing logs and restarting the configuration and then gbpvr app.
When in gbpvr, I went to the EPG, selected a channel, waited a few seconds and then went back to EPG to select another one and repeated the sequence.
Again, the two channels working were the first one and the last one. The second and third show only black screen and no sound.

Sorry, I dont really know. I cant see any obvious cause in the logs.

What should I do next to help debug this problem?
Is there a way to turn on even more verbose logging and perhaps getting logs from DirectX and the drivers?

To be honest I dont really know what to suggest. ATSC is a bit of mystery to me. We dont use this here in New Zealand, so its not something I'm particularly familiar with.

If two of the channels are working fine, then it sounds to me like its not failing to lock onto the signal for other channels. Using the VMR9 Custom renderer, if you switch to those channels in live tv, then press Ctrl-O, do you see a signal strength meter?
