I'm in a similar boat. For ages it was my hdpvr that would lockup and give
0 byte recordings. Now it records ok, but the IR channel changer (mceusb
blaster) is locking up. That's bad enough but my kid watches TLC all the
time directly through the SA4250HD - so I get great quality recordings of
crappy shows instead of what I scheduled...

The worst part is sometimes even a shutdown doesn't seem to reset the USB
bus. I can't repeatably get back to a working ir blaster.

Can anyone recommend a workaround for that? I'm hoping to avoid buying new
hardware as Enigma did...
