Tried upgrading to 3.0.3 today. But hit this issue and dropped back to 2.2.8....
Hardware: Windows 7 + i7 (6Gb Ram) + Quadro FX370 Graphics - yeah I know, not exactly a hot machine.
Media: MOV clip taken from an iPad (1920x1080 H264 @ 29.97 - 44.1 KHz audio)
Symptoms: Playback in 3.0.3 only showed a few frames. Often only a single frame. The seek bar proceeded as normal, but no video.
Audio plays correctly. It looks rather like CPU starvation, but CPU load is minimal (a few percent max).
In 2.2.8 both video and audio play fine. CPU load is higher (say 8-10%).
I'm wondering if there are some new hardware requirements (esp' GPU) for 3.0?
