for main profile H.264 streams. I have tested this on all H264
conformance streams and comparing the result with the current CVS
version, there is 8 streams which decode correctly more frames and 2
streams which are now completely correct with my patch.

This patch also correct some typo in comments.

some sanity checks on what is muxed, invalid timestamps in mpeg are very common and lead to strange errors in the mpeg muxer otherwise
