[vdr] Re: ERROR: skipped 28 byte to sync on TS packet

[Carsten Koch <Carsten.Koch@icem.de>]

Hi Bernd,

thanks for the benchmark results!
This is very encouraging.
It gives me another reason to feel good about the
time I spent to convert my file systems to XFS,
install the XFS kernel patches, etc.
(not that I was not confident already)

Which kernel are you using?
I have been running 2.4.16 with XFS for a long time
now and I am planning to go to 2.4.17 very soon.

Carsten.
