Thanks both, this project was handed off to me by a client so it’s a little difficult (he has had no problems)! if I open the mpeg 4s in Qtime their frame rate is not dead on 25 fps, more like 25.18, this is an issue I guess BUT BUT BUT I did a little more digging and found that some people were having problems with Quicktime caused by the “EyeTV MPEG Support component” in Library \ Quicktime – removingit seems to have helped … I think … I’ve only just dumped it so I have fingers very crossed. Thanks for taking the time and I’ll keep this updated in case it’s of some use to others. Regards Roger
