[mythtv-users] Slow video on XFS raid 0, ok video on ext3 on single drive.

Hi folks!

I have two Seagate 160gb drives in a RAID 0 array on an SiI0680 PCI ATA raid
controller. I formatted an XFS filesystem on a single partition, and set
mythbackend to use it. My DVB card is a DviCO Fusion Gold 3,( Conexant

When I watch live TV, I get terrible artifacts on digital TV, and slow frame
rates on analog. When I reset mythbackend to use a ext3 partition on a
single drive, performance is acceptable.

I went to considerable trouble to get the RAID and XFS working on my Fedora
5 system, and it's pretty discouraging to see that it actually degrades
instead of enhances performance. What is likely the problem? Is it the
controller, the raid or the filesystem?

Thanks for any advice!
