Yes, the missing PCR is a big problem, but not the only one...

I do not think so... In my experience, even if the PCR field is
correctly filled the mpegts muxer will still produce streams that cause
buffer overruns/underruns in most set-top-boxes (this problem is not
visible using a software player, because it generally has larger
buffer).
I noticed that changing the PES size fixed some of such problems
(because audio and video packets can be interleaved in a better way). Of
course, as M?ns pointed out the PES size is not the real problem, but
changing the PES size is (in my experience) the easiest workarond.
