This question only applies to people with a PVR-350, apparently:

When the "default" recording profile was set at 480x480 [which is the
default for the mandrake 9.2 RPM], I got an MPEG 2 muxed file that had a
resolution of: 480x360.

So I followed your advice, and changed the 'default' recording profile to
704x480 and now the resulting MPEG2 muxed file has a resolution of
640x480.

I am very confused as to how/why this is happening. I would like MythTV to
produce 704x480 MPEG2 files so I can easily burn them onto DVD on my OS X
Mac. I'm not able to make many changes in MythTV's settings, as I can't
see them on screen [X and the mythfrontend program both display at
720x480, while my receiver/TV/PVR-350 seem to only display 640x480]. I'd
like to fix the X issue first, so I can use the MythTV GUI to change
settings, but I haven't found any post in the archive stating that one's
XF86Config-4 should be 640x480 for the PVR-350 [so far, everyone's posts
i've found all state 720x480, which is clearly too big for my TV].

Do the recording profiles only affect MythTV's software encoding? I'm only
using the 350 to encode the TV signal. Is there any way for a PVR-350 to
generate 704x480 sized video without transcoding?

Thanks,
