Generating H.264/PAL DV High Quality is hanging

Hi all,

I'm struggeling to generate MP4 files from Adobe Premiere CS5.5.

It seems that the Media Encoder works fine for a long time, but then suddenly stops processing. The application is working, but it is not possible to contiue generating the file.

I've been generating 14 files without problems, but the 15th just keeps hanging.

Any idea what the problem is?

I'm on Windows7 , 8GB memory and plenty of CPU.
