We support this opinion btw.
The rationale has always been that our support for this had never been 
upgraded to the final standards. Mostly also because very little 
programs up until now have been capable of handling mpeg4 in TS, so it 
wasn't very critical.

Just to let everyone know, Gildas even yesterday made some changes to 
properly mux MPEG4 into TS
http://trac.videolan.org changesets 11215-11223

What is left to be done is the MPEG4 audio muxing as far as I know, but 
this is considerably more complicated then the video muxing Gildas told 
me. Help is always welcomed of course.
