FWIHH, one of the strength of reiserfs is, that it is "fscking ;-)" fast
on small files compared to other fs. on the other side xfs is claimed to
outperform the others on very big files. so regarding to vdr, i would
prefer xfs anyway.

IIRC, bandwidth reservation is not implemented on linux yet. but i could
be wrong.
