 Replying to [comment:4 michael]:

 it is black screen but has sound.
 i learned a lot and found that it is because the muxrate is too large.

 timestamps, of ?

 please explain why you think they are wrong. A reference to a specific
 section of a specification would be best.

 the scr is always begin with 28616 either than 0,i mean the first
 timestamp is 00:00:00.50 not 00:00:00.00

 > what muxrate did you specify, what was stored, what did you expect? what
 tool did you use to see its wrong.

 i didn't use "-muxrate" and the default muxrate estimating is not correct.
 when use "-muxrate", it is correct.

 > > 3. i think the PCR is also buged, it's not begin with 0, the SCR base
 is not begin with 0, either.

 not PCR, i mean SCR system clock reference base
