Thanks for this, I tried it and it worked perfectly.
After some testing I'm becoming convinced that the real problem actually lies in the B-VOPs. I'm no video-encoding expert, but according to wikipedia, B-Frames are frames that need to be decoded BEFORE the current frame, the problem I was having was the X20 displaying a "future"-frame through the current one, so the problem probably lies here :O . This doesn't explain why it did work on firmware 1.02 though.
Again thank you for this information
