First, what are the specs. of the source files and what is the Project's Preset?
Next, what is the make/model of your video card, and what is its driver number/date?
Those are the first things that I would look at.
The source files are AVCHD 1920X1080 (from SONY HD camera).
Video card (according to specifications of my computer)is:
- 1GB ATI Radeon HD5870
- ATI(R) Radeon(TM) HD 5870 CD kit
Will provide Project's Preset in couple of hours (don't remember it at work in the moment, except that it is HD, Pal and H264 I think)
But I am not sure how to find driver number/date
For the driver info, you can go to Control Panel>System>Hardware>Device Manager>Display Adapter, find the video card, Dbl-click on that, then Advanced>Driver.
Remaining technical details:
1. Project setting PAL-AVCHD-FullHD 1080i 25 5.1 channel
2. Video card ATI Radeon HD5800 series
3. Driver ATI Technology
I actually updated the driver to the above version today, but still have the same problem
Was your footage taken using 5.1 audio? If not you will need to use the PAL-AVCHD-FullHD 1080i 25 one.
Check you have the latest Quicktime version (7.6.9 at today's date) and Sound Card drivers.
