I've encountered this as well and found that running the mpeg-TS file
through mencoder to create a mpeg-PES file cleaned up the file error
and made the file playable.

There is also a script someone wrote that discards the front of the TS
file until it encounters the first sync byte ..... I haven't tried it but I bet
that will work as well.
