After about a year of reliability with gbpvr, I have moved my card (Hauppage WinTV Nova 500) to a new PC (running XP). I also elected to load NPVR and although things are ok most of the time, I get occasional failed recording with:
2011-05-04 21:10:30.703 [INFO] About to start BDA graph
2011-05-04 21:10:30.703 [DEBUG] Starting graph...
2011-05-04 21:10:30.703 [DEBUG] Failed to start device: 0x8007001f
2011-05-04 21:10:30.703 [DEBUG] Removing filter MPEG-2 Sections and Tables
I also notice that sometimes a recording is split in two as if there was an interruption. I am not sure what the logs are telling me, so hope someone can point me in the right direction
