IT WAS MY FAULT, GUYS.. SORRY.
This has been fixed and committed. If this bug made it to 0810 on accident, then a new mythTV player will need to be made.
Basically this is what happened:
I had made a replacement screen for 1004 to replace the awkward MythTV is displaying something other than TV screens for on-screen orbiters.
To facilitate this, I had replaced the Get Video Frame command, to output a complete picture of the Mythfrontend window to present on the orbiters (which it updates frequently)... The resulting designer screens were checked into sqlCVS accidentally.
To make matters more interesting, during the branch move from 0810 to 1004, I had lost this chunk of code that I was experimenting with, so I had to rewrite it again...so, why was this needing to be rewritten? well...
the ORIGINAL get video frame command never worked properly, it tried to send a command to mythTV to take a screenshot, which, had the unfortunate side effect of sending keypresses to the myth Ui and just making a total mess. Combine that with the fact that this was happening multiple times, yes, all hell broke loose.
So, to fix:
* I wrote the Get Video Frame code from memory
* I merged in Simulate Mouse Click from memory, to deal with mouse presses inside the viewable frame.
This fixes the problem.
Again, sorry guys that this happened. My bad.
