While recording to internal drive (fat32) I'm getting momentary picture freezing/studdering on PBS East HD on AMC 21 while watching it being recorded at the same time(not time-shifting). When I stopped the recording and watched the recorded program from the internal drive the breakups didn't happen during playback of the recording. I thought this is very odd. Could it be a overheating issue or limitation of the processor? Thanks.
When testing both in the office and at home, I did not observe picture stuttering, let me do some testing with and without the heat sink.
