I have disabled the both, the cpu usage seams to be much lower now. The
same is true with the number of interrupts. They are now about 1100 per
runing recording.

I have similar problems. But the same was true with 1.0.4. I had several
recordings where the play mode was changed automagically to fast forward
at a speific point of the recording. Jumping over the localtion helped.

It looks better now. Still not the same level as 1.0.4, I now have about
15 % usage per running recording.

This may lead to corrupt files if data is lost.

I once compiled one to be used by my tool vdrls which shows the
resolution and aspect of recordings. This version seems to ran stable. I
tried also other tools but got core dumps for them. If you want my
streamtype binary I can send it to you.
