I don't see how a constant shift on the timestamp of an ES would affect the
decoder. Timestamps are only meanignful relative to one another, not as

I would certainly think so.
Now the problem is when the user changes the delay. Obviously the postponed ES
will have to "pause" while the other catches up, or the advanced ES will have
to "skip" forward to catch up. AFAIK, it already necessarily works that way.
