  weird video problems with Leopard and 8800gt

  Hey all,

  I recently bought a macpro to replace my old power mac G5 since i was working more with HD video and needed more processor power to ease the ridiculous processing times.

  Anyway, I have been experiencing some weird video problems with FCP and quicktime that I am wondering if anyone else has noticed or have a solution for.

  First off, here’s the important facts about my computer-
  – Mac pro dual quad core 2.8 gig
  – 2 gigs ram
  – FCP 5.1.4
  – Geforce 8800 GT video card
  – 30″ HD display
  – Leopard version 10.5.2 (and all system/software updates installed)

  Issue #1: I have noticed that in my viewer (not external monitor) when I am playing back video from the timeline, sometimes there are some odd lines. Looks kinda of like a scanning issue. If I export the video or watch it on my playback monitor, however, it is not there. This problem doesn’t actually hurt anything, it just bugs me and makes me worried if I had a legitimate problem with a piece of video, I would overlook it. Also, like i said, it happens randomly. I can even play the same part of the timeline that just played with the problem immediately after, it the lines are gone…but then the next time they are back sometimes.

  Issue #2: Again, this only happens sometimes…but sometimes when I playback exported video in quicktime (I purchased pro and have my code inputted) it will strobe the video but the audio plays back fine. If I then click on my desktop (so quicktime is not selected in the foreground) the video plays smooth. I can recreate these results by clicking on the quicktime window and then back off again. Again, doesn’t seem to harm anything, just obnoxious.

  My only guess was that there is maybe a driver problem with the 8800gt, but I have searched everywhere and all I can find (even on the geforce website) is that OSX leopard has native drivers for the card, and there is no update/download.

  I have also been wondering why there isn’t a control panel for my video card on this comp (I thought maybe I’d find a forced driver update option in there). With my old computer, I got a geforce card after I purchased the computer, and after I installed the software, it put a geforce control panel in my system window. That was on Tiger tho…so I don’t know if it’s a OS difference.

  Any clues would be appreciated tho from the searching I have done….I’m not sure if this is a known thing or if there is any sort of solution yet. . :/

  thanks,
  Damion
