In my experience, the ivtv drivers do best at 480x480, 640x480, and
(best of all at) 720x480. So, the one overlapping resolution is 720x480
(and that happens to be the resolution I use).
If your recordings are actually coming out at 480x480 even though the
card is being told to use 352x480, it's a driver problem (or possibly a
constraint on the hardware). So, you'll probably get the best
information from the ivtv mailing list.
