I may well be doing something wrong, but I'm still seeing some
clipping on my captions. It's noticeably better than it was, but still
clipped.

My input is analog cable, NTSC (so whatever closed-caption format that
would be), captured with a PVR-250.

I'm running trunk from late Sunday night... I forgot to grab
"mythfrontend --version output" ... I can get that tonight, if needed.

What I see is the first and last letters on each line are slightly
clipped. At least the captions are readable now, but they're still
clipped. I tried lowering the "caption zoom percentage" from 100 to 50
to see if it made a difference but it did not... in fact I didn't see
any difference at all, so perhaps that setting doesn't do what I
thought it might.

It is a big improvement over the clipping the ticket was originally
opened for, but it's not as good as it used to be. :)
