hi david,
check your error logs for compressor in Console to see what’s causing it to crash. usually its a framework that’s gone corrupt. like the helium.framwork.
delete all plists and prefs and compressor and reinstall.
it could also be quicktime causing the problem. if so, again delete all plists and prefs and reinstall.
and make sure you fix disk permissions 3 times before you reinstall your apps. and fix disk permissions again after you reinstall. i’ve had to reinstall both a couple times in fcs1. but so far its been clean sailing in fcs2.
also, don’s workflow is correct if you want the utmost quality. and you can only get it if you send from final cut to compressor. but this ties up your system. i’ve talked with him on this subject and i use it if i’m not on a deadline.
the majority of the time, i export ref movies and throw them into compressor. this doesn’t tie up your system and the quality hit is usually acceptable.
but using either workflow will not produce the artifacts as you are discribing. which is why i’m thinking its quicktime or compressor that’s giving you the artifacts.
and yeah, i also have a panasonic dvd burner connected to my i/o kona 3 just like walter does when i can’t wait for compressor 😉
