Hardware encoding with PVR-350?

Post #1 of 4 (1234 views)

I have a working MythTV system (mythtv-suite with mythtv 0.10) and would
like to use my PVR-350 capture board to encode MPEGs. I tried enabling
hardware encoding by setting "TV Settings"->"Recording"->"Default" to
"Hardware MJPEG", but nothing was recorded. Specifically, empty .nuv files
were created. The only other option is MPEG4, which the PVR-350 doesn't
support. What am I missing?

Go into the backend setup program, and make sure you choose "Hardware MPEG
card" as your card type. The codec selection in the frontend recording
setup will be ignored, and you'll have standard MPEG-2 recordings with a
.nuv extension.

Those settings are ignored with the PVR-250 and 350. The only setting
which really has any effect is the recording resolution.

Follow the ivtv instructions to troubleshoot your card.

Cool. I verified that the .nuv files were really MPEG-2. It was doing
what I wanted all along.
