SATA CD/DVD recording fails on Etch - MSI K8MM-V

[KEBRA <kebranegest@gmail.com>]

Hi everybody, after trying for a couple of weeks, I decided to ask you 
about this.
The installer recognizes perfectly (I guess) all drives and the 
installation works fine, no errors, everything ok. I can read perfectly 
any CD or DVD, but when I try to record, kaput.
The records process starts ok, but somwhere in the middle it crashes and 
K3b shows me the error once the recording is done, and I end up whit 
corrupted files.
The recording speed is also very slow.

I've been searching the web and found a driver on viaarena.com but it 
doesn't work with my kernel.

The chipset is VIA K8M800-CE + VT8237R.

Thanks in advance for any help you can give me.
