No, but there are other fixes in libmpeg2 in version 0.3.1. I have applied the 
patch to xine CVS, which should not cause any other side-effects but a slight 
performance hit (more L1/L2 cache is used).

Thanks for your explanation. There are some MPEG-2 streams not working 
properly. I was hoping that merging libmpeg2 version 0.3.1 with xine would 
fix those streams.
