Good point... I may be demanding too much out of an old system. I'll test
lowering the resolution this weekend.

I have actually seen the video card die (output freezes in corrupt state or
just goes black) a couple of times when the system was loaded with two or
more recordings running and playing back a third with timestretch and zoom.
Thankfully recordings continue just fine and the rest recovers after a
reboot.

Maybe it's time to do a server upgrade... but since I spend days researching
a simple SSD purchase I think I'll wait until summer vacation with that one.
