I saw a similar issue when I upgraded my existing system from 0.24 to 0.25. 
When recording more than one show at a time (via 3 HDHR units), the 
recordings has moments where they were almost like a bad signal.  Lots of 
"pixelation" where the screen would get all "artifacty" and when that 
happened, the sound would get that metallic almost robotic twinges in it.  I 
don't believe it's a hardware issue because as soon as I switch back to 
0.24, no problems what so ever.
