[vdr] Re: Best video card for 1080i/p with softdevice?

I am using an nVidia 6200 TC so I can also offer some perspective for
"best video" card question.

I'm reasonably satisfied with the 6200, it does MPEG2 decode in hardware
and it's passively cooled.  I am not using DVI/HDMI, but it does have
DVI+VGA+TV-out, so it should probably work fine for you.

I prefer to use softdevice for display and until very recently, there was
an issue with OSD corruption.  This bug has been fixed (in softdevice
CVS)!  So, the card for sure works with softdevice.  But softdevice does
NOT support XvMC and there is no indication anyone is working on that.
In other words, your CPU load will be high playing back HD content.

I have also tried Xv output with xineliboutput and that seems to work fine
too.  Xine-lib using XvMC (or xineliboutput) seems to cause corrupted
video for me, while mplayer deals with XvMC perfectly.

I say if you have an AGP/PCI system, consider the nVidia MX4000.  I
haven't used it myself with VDR but it supports XvMC (MPEG2 decode) and
it's passively cooled.  How good is the hardware de-interlacer?  That is
unknown to me, maybe someone else can comment.

How do you enable the de-interlacer seppo?

What version of xine-lib and X.Org do you use?

As I mention above, I also have issues with xine-lib and XvMC on nV 6200
(whether it's xineliboutput or just playing an MPEG2 file with xine-ui).
I was using xine-lib CVS June-2006, and X.Org 6.8.2.
