Hmm I have some problems with ext3 here. I suppose its the writing of 
the journal. I get full speed at copy in the beginning and after an 
amount of time the speed breaks down and after that it speeds up again. 
Very annoying. I want to test XFS later and see if it is better. Reiser 
is Ok for small files and a lot of them, but i don' have a lot of small 
files with vdr and i had some bad experiences with an older version of 
reiser. The only problem i may have with XFS could be compatibility... 
(could there be any backdraws in that direction ?)
