Let me try with latest kernel (2.6.7), vdr (1.3.12) and softdevice
(0.0.7pre1).

But since the problem disapear when I stop vdr process, I think
there's a timing issue between some buffers that are emptied before
they are filled or vice-versa.

Regarding timing, the biggest difference between your setup and mine
is the pre-emptive kernel. I'll try to disable this feature to see if
it changes anything.

No problem. I did not resend the message because I was on vacation for
the last 2 weeks.
