try to print debug traces with playbin2 and figure out it's pipeline.
i hope the sync issue isn't seen with playbin2 ?
in my case, a streaming asf source plays pretty well (no observable
sync issues), but in my "optimized" pipeline, which was built by
observing playbin2, doesn't fare so well. I think in my optimization
drive, I've chopped off some necessary "sync" elements. recreating the
playbin2 pipeline using discrete elements on command-line, completely,
has been a challenge.

i hope someone can shed some more light on this subject.
