Hi, I gave up on bob after reading that it ONLY works with a 50 (or
perhaps 100 Hz) refresh rate. The closest my flatpanel will go is 75, and
I can confirm that that doesn't work. So I think 60 is most probably out
I'm also having frame dropping issues, someone posted that it is a problem
with myth at the moment (don't know what you built from). It's evidently
expected to be fixed soon in svn. You might also like to check whether
your running the frontend in realtime priority.
Looks like I'm heading for IVTV 4.x :-)
