Btw. is there an easy way to see this from the logs because my vdr box 
is situated in a difficult place where I can easily get only by ssh?

I found this for the non recording disks
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on pci0000:00:0f.1
    ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:pio, hdd:DMA
hda: 30015216 sectors (15367 MB) w/512KiB Cache, CHS=29777/16/63, UDMA(66)
hdd: ATAPI 40X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(33)

and this for the recording disks
ata1: SATA max UDMA/133 cmd 0xE800 ctl 0xE402 bmdma 0xD400 irq 169
ata2: SATA max UDMA/133 cmd 0xE000 ctl 0xD802 bmdma 0xD408 irq 169
ata1.00: ATA-6, max UDMA/133, 390721968 sectors: LBA48
ata1.00: configured for UDMA/133
ata2.00: ATA-7, max UDMA7, 156368016 sectors: LBA48
ata2.00: configured for UDMA/133

I assume this means DMA is enabled.
