Ville,
Yes, the mplayer performance is poor, on par with VDR.
Per your suggestion, here is the lspci -v and /proc/mtrr info:
lspci -v:
01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G550 AGP (rev 01)
(prog-if 00 [VGA controller])
Subsystem: Matrox Graphics, Inc. Millennium G550 Dual Head DDR 32Mb

Memory at e4000000 (32-bit, prefetchable) [size=32M]
Memory at e6000000 (32-bit, non-prefetchable) [size=16K]
Memory at e7000000 (32-bit, non-prefetchable) [size=8M]
[virtual] Expansion ROM at e6020000 [disabled] [size=128K]

Kernel driver in use: matroxfb
and cat /proc/mtrr:
reg00: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1
reg01: base=0x10000000 ( 256MB), size= 128MB: write-back, count=1
reg02: base=0xe4000000 (3648MB), size= 32MB: write-combining, count=1
reg05: base=0xe0000000 (3584MB), size= 64MB: write-combining, count=1
Does this look good?
Thanks!
Olek
