Very weird neon green & pink playback problem?!
OK, this is a really bizarre problem, I am completely stumped. At first, I thought it was a DVDSP issue, but after more investigation and a visit to the dvdsp forum, it appears that’s not the case. Since there are almost three times as many forum moderators in this forum than there are over at DVDSP, hoping the collected brain trust can solve the problem.
In a nutshell, in certain apps – dvdsp, toast, & dvd player, all dvd files – whether assets encoded in compressor or store bought dvds – play back neon green and pink. In toast and dvd sp, when parked on still frames, the files look fine – the problem is only on playback.
In mpeg streamclip, QT, Compressor and using Quicklook, the identical files play back fine. I believe the assets are fine – when burned in toast, the dvds play back fine on all other players otehr than my G5 quad core.
I’ve tried all the obvious – deleting prefs for all of the above apps (except compressor, which doesn’t seem to have a .plist file in my prefs folder), running disc warrior, repairing prefs, you name it, all to no avail. Ran techtool deluxe, all hardware checks out fine. I’ve got 4mb of ram from crucial that’s been in there for over a year. No other problems in any other apps. My Kona LHe drivers and ATI x1900 are both updated.
I upgraded to Leopard with a clean erase and install about a month ago and reinstalled fcp studio, ran all the updates, have been running 6.04 on a G5 quad core with 10.5.5 daily with no problems. I think this is the first time I’ve used dvd sp since the update.
Because the files play back fine in some apps, I’m pretty sure it’s a software issue. But where?!
I’m tempted to update to 6.05, but don’t want to make things worse. I am completely stumped. Could it be a hardware issue?
I know this is sort of OT, but my guess is that the only people who are going to have a chance at figuring it out are FCP people, and that any apple tech is going to give me the blanket advice of wiping my drive and starting over, which I really hope I don’t have to do.
Ideas?

OK, I came across the cause of the problem, figured I would post it to save others the trouble, as it is caused by a set of circumstances other FCP users may encounter.
Seems the combination of 10.5.5 and ati x1900 cards in G5 quads is the culprit.
Here’s the full discussion on the apple forums.

Some people have reported 10.5.6 fixing the problem. Just tried it and it did in fact work for me.

I too had these green and pink frames while I was cutting a feature. MANY MANY calls back and forth to Apple. Like you, I have a Kona LHe card, but I am using 2 nVidia 8800 cards in a MacPro. I tried everything I could imagine including full clean installs of the OS and FCP suite (a number of times). Apple even swapped out the logic board, power supple, all 8 Gigs of RAM, the memory risers, and video cards to no avail. I transferred the footage from the G-Raid to internal drives assuming it may be a drive issue… Nothing helped.
Finally, I transcoded all my footage from XDCam to Prores and that fixed the problem… I assumed it must have been some weird way the long GOP Sony XDCam codec works with the mac….
Was your footage XDCam by any chance?
