Comment 11 for bug 707239

I may have this issue too.

I created a simple project, consisting of one video file (1920x1080@60fps, mp4 file from a sanyo xacti cam), that I devided into 3 parts.
I put the 3rd part infront of the 1st part and discarded the 2nd part.

if I use the defult output setting: 576p (PAL, 25fps)
oggmux, vorbisenc, theorsenc
it renders fine and plays well.

but if I use different settings, like matroskamux, faac, x264enc (which should yield the same hd video files,
found all over the internet.) the render process never starts.
there is no increase of cpu usage or disk access or any other signs that the process is just slow and there is is big workload.
