Video Display Problems on iMac
I am having difficulty with CS5 Premiere Pro on an iMac3.33GHZ which comes with an ATI Radeon HD 4670.
I have been using Premiere Pro on another iMac without problems and can’t really remember whether I have ever had it successfully running on this machine before.
Importing a .mts file shot on a GH2 at 1080i 50 (I am in PAL land) produces incredibly jerky footage which needs to be rendered before it will play properly – not the case on my other machine or a macbook pro. Also Premiere prides itself on not requiring endless renders. The real problem is that once rendered, it appears to play back fine but if I maximise the frame in the viewer the entire screen goes black – something is playing behind it but nothing other than a restart will solve it.
I have not had trouble with any other application and Tech Tool Deluxe says that the video ram is fine. Is this likely to be a Premiere Pro problem or a hardware problem? If Premiere – any solution or should I simply do a complete uninstall and reinstall.
Thanks for any tips.

Your video drivers maybe corrupt, try reloading them.

Actually I think it was that something in the program that got corrupted. I backed up all my projects and uninstalled and then reinstalled. Everything works fine now. The only thing I didn’t do was upgrade to 5.0.3 and have used the version I bought – 5.0.
These programs are becoming too complicated and fragile. I also have FCP and that is starting to crash every time I use Log and Transfer and set the in and out points by scrubbing in the viewer. Never did that before. So I shall uninstall that and reinstall.
