Nope, Scott, not true.

I still think it must be YOU ;-)
I've had my recording profile set to 480/480 and it works
just fine for me. So what ever it was that you fixed by setting
720/480 was tangential at best. BTW, I'm using ck115e
and myth 0.16. My high-quality profile (which I never use) is
the only one that has 720/480.
So the fix posted on ivtv simply masks the problem that must
be somewhere else, or it would fail ( "Chipmunk" ) for all of us.
As Isasc pointed out on the ivtv list:
"What makes you think that 720x480 is better? It's an analog signal, the
horizontal sampling rate isn't coming in to the capture card at _any_ given
number of pixels. Why do you think a recording made at 720x480 (ie, with a
pixel aspect ratio of 3:2, not 4:3) doesn't play back letterboxed when
displayed on a standard 4:3 monitor/television?"
