This is based on Debian. I have Debian-Sid _and_ Suse 10 on this machine. With
Sid mythtv is unusable, it is a _lot_ slower. I have no idea why, it is the
same hardware. When I start KDE, the initial sound is interrupted with Sid,
but not with Suse.

Hmmh, maybe I exchange the card.

I use PAL with DVB-S from Astra and Hotbird on the backend-machine. At the
moment there is no chance to scan Hotbird, while Hotbird (Diseqc) works with
scan and Kaffeine.
Why is the harddrive important, it is a frontend?
Backend:
Timing cached reads: 1292 MB in 2.00 seconds = 644.67 MB/sec
Timing buffered disk reads: 102 MB in 3.03 seconds = 33.64 MB/sec
Frontend
Model=ST380021A
Timing cached reads: 544 MB in 2.00 seconds = 271.98 MB/sec
Timing buffered disk reads: 36 MB in 3.01 seconds = 11.95 MB/sec
DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5
smbios.bios.version = 'ASUS P2B ACPI BIOS Revision 1014 Beta 003'
I think this is too slow for this drive.
WIth a fast machine and the same model I get with these values:
Timing cached reads: 1360 MB in 2.00 seconds = 680.10 MB/sec
Timing buffered disk reads: 100 MB in 3.04 seconds = 32.85 MB/sec
Maybe the hd is connected with an old IDE-cable or the ASUS P2B supports only
udma2.
