[mythtv-users] PVR250 Settings?

Probably because I don't necessarily know what I'm doing. :-)
I played around a bit and this seems to be ok.

About transcoding though, I'm going from MPEG2 off the PVR250 to
MPEG4...at least that what I think I'm doing. As far as the bitrate, I
really didn't know what the bitrate does for the transcoding setting so
I left it alone. I guessed that since MPEG4 is compressed the bitrate
setting doesn't mean much on the output file side so perhaps it might
be limiting the sample rate taken from the input file.

As I said, I'm guessing at a lot of this.
