It ends up that mythtranscode was not resizing the video. My frontend
was crashing any time it tried to play video bigger than the screen. I
got it to resize and playback looks really good compared to the analog
recordings from my PVR-350 (can you say snowstorm?).
Anywhere I can find pointers on getting the aspect ratio right? The
HDTV signal is broadcast for a wide screen TV, but I just have a
standard TV. I end up with black bars on all sides of the video. Also,
is there anyway to transcode to MPEG2 so that I can use the PVR-350
hardware decoder for playback? I tried to get nuvexport running, but it
just gets errors on FC4.
