It has been a while since I read the White Papers from Brooktree (the folks that invented the TV tuner business and the BT-XXX chips), but I seem to recall that 640x480 is the maximum for the NTSC chips, while PAL can go a bit wider, but not 720.
I use ShowShifter for all my recording needs. For archiving, I use Pic Video's MJPEG codec (comes with ShowShifter) which offers light compression/highest quality and is easily edited. Once that is done, another program can be used to compress to MPEG or WMV9 if desired.
For day-to-day recordings, I use Divx or WMV7.
ShowShifter added 48 kHz last year.
