fine

The module from the patched kernel should do very well.
(Ain't it the same like the CVS version?)

Do it as a module, so you can "insmod" the module with the appropriate parameters before starting VDR.

No

No

I'm using last month's CVS version, which does well.
I added a patch from Colin (search for Colin), which imports a faster copy function

Additionaly I used Colin's test version of the CLE266 hardware decoder.
You may not need it because your CPU seems strong enough to do software decoding of the MPEG stream.

Everthing, which is described in the softmpeg dokumentation

look in the mailing lists, there are some example modeline

I think, the TV resolution (TV=1 option) works best.
This way, the picture doesn't have to be transformed.
Select whether to use PAL or NTSC (TVtype=  option).
