After getting my player fixed, the button delay now only happens 10% of the time, and 100% of that time is when the HD icon is on in the upper corner.
Other things that happen are:
No responce from remote
Hijack gets confused

And this happened last night to me. While connected up thru a serial connection, watching the player, ALL output froze, and no input would be accepted while the HD icon was on. Once the HD icon went off, I got a backlog of all the data that SHOULD have been written, but wasn't.

This may be already known, but I didn't see anything, and workign in support myself, I know sometimes that the more information, the better.

Me.
