The Kfir card works pretty good with VDR and my 'sky' plugin.
However, there are two drawbacks: one is that there is a green, dotted line
across the bottom end of the screen, which apparently is caused by the
modules of the 2.4.10 kernel I am using. If I use kernel 2.4.18, this problem
is gone (however, with that kernel DMA doesn't work with my HD).
The second, more serious problem is that when I use the Kfir driver in TS mode
(which I have to do since VDR requires a Transport Stream) only the very first
recording after loading the Kfir driver works fine. Every following recording
has heavy artefacts at the bottom end of the picture, and this gets worse with
every further recording. Apparently something in the driver isn't reset properly
when closing and re-opening the device. I have reported this problem several times
on the mpeg-2 mailing list, but nobody was able to come up with a fix :-(
So currently I have to reload the Kfir driver after every recording...
