Is there a chart or FAQ somewhere which covers bitrates to use [esp. with
your recommended, 704x480 resolution]? Also, given that I have a PVR-350,
which appears to output 640x480 [at least on my TV], should I switch my X
session to use 640x480 resolution instead of the 720x480 that Jarod's
HOWTO shows?

One more resolution question - in the recording profiles, all the profiles
list 480x480 [eg: live tv, default, high quality and low quality]. But the
mpeg2 files that my 350 produces are all 640x480. If I change the default
recording profile to 704x480, will this change the mpeg2 output?

Thanks,
