Sorry, that's 50% during playback. I don't know about recording, but it's very low. > My first guess would be that you should make sure DMA is working.

Certainly nothing from dmesg during regular SDTV recording, though I didn't check after the HDTV recording in particular. Are you able to download my recording and try it on your system?
