I indeed had some RAM problem which triggered failure of "burnMMX
P". This problem is now fixed: I concurrently ran "burnMMX P" for at
least 30mns without a problem.

Nevertheless, I still have seg fault when encoding vdr files with
mencoder qith this command: 

mencoder 'vdr_cps/%_/2006-06-05.17.20.90.99.rec/001.vdr' -oac mp3lame -lameopts preset=120 -vf pp=ci,crop=688:544 -ovc lavc -lavcopts vcodec=mpeg4:v4mv:vbitrate=1000:mbd=2:trell:vpass=1 -o 't_vdr_cps_%_2006-06-05_001.avi'

Currently all tries lead to a seg fault. 

Here's one backtrace with mencoder:

Core was generated by `mencoder vdr_cps/%_/2006-06-05.17.20.90.99.rec/001.vdr -oac mp3lame -lameopts p'.
