hi there, i'm seeing a strange issue on tuning to my local abc channel. i realize the signal quality isn't that great on my antenna, but it never shows up on the scan list (i've tried 2 different tuner cards - an ati tv wonder 650 pci and an ati tv wonder 600 usb, but neither showed the channel, even on a manual scan of the frequency. it does show some quality / signal strength numbers but no channel shows up.) i tried the usb tuner on my laptop and the missing channel was found, so i copied over the tuning line into my desktop's scan.cache file, and under the mapping config page i was able to see the channel in the preview window and map it to my EPG channel. but when i start up the app normally and go to the channel, all i get is a black screen...

here's the log of it trying to tune in to the channel:

Assuming the strength and quality values are on a 0-100 scale, those reported values are way too low to tune a digital signal. Even a 0-50 scale they would be too low. Signal should be >80% for ATSC and > 90% for QAM and quality should be near 100% for both. What values do you other digital channels show?

Edit: It's not even registering a signal (present=0). Not sure why that would be since even a low signal should show as at least being present. I could be wrong on that though.

other channels quality values are in the 70-100 range. although it seems to me that since it shows up just fine in the preview mini window in the config app, it should also work in the main app O_o

View the channel in the config window and zip and post your config.exe-native.log and config.exe.log file.

strange, since here quality is over 80...
also something i'm seeing which may be related is that since i added the channel, pvrx2.exe randomly loses the signal for all channels... and then crashes when i restart it... i'll attach all my logs in a zip, maybe someone can figure out what's going wrong.
