[vdr] dxr3 issues

[Dominic Morris <dom@suborbital.org.uk>]

Hi,

I've finally bought some hardware and my vdr box is now up and running
with a Nova-T and the obligatory dxr3 card.

I'm currently running with vdr-1.2.0 and the latest 0.2.0 dxr3 plugin with
the 0.13.0 kernel module. A hacked-up script is combining schedule
information from tv_grab_uk and tv_grab_uk_rt to provide full scheduling
coverage.

Anyway, most things seem to work, though I've run into a couple of
problems which I'd appreciate some input on to solve, both of them are
dxr3 related.

- Playback of recordings seems to use up far too much CPU - typically
around 40% with most of that spent in system calls (yes, dma is enabled,
and toggling it makes no difference to vdr, but does to hdparm -t). This
appears to be happening in the thread with a stack trace of:

(gdb) where

Though that probably isn't of too much use!

- The CVS version of the dxr3 module which appears to support the latest
(CVS) lm_sensors i2c code (handy since my nforce2 motherboard needs it),
results in a black and white picture only which is novel.

thanks for any help,

cheers,

d.
