I have a few dedicated VDR setups which all have a combination of
Nvidia GT2xx cards + Sony & Panasonic receivers and tv's. All are
connected with hdmi only. I did use VDR + vdr-xine + xine-lib-1.2
vdpau and never experienced the problem you described. I switched to
vdr-softhddevice instead of vdr-xine/xine-lib-1.2 and still no
problems here. Doesn't matter if the receiver, tv, or both is off when
VDR is started, it always works. I didn't do anything special but I
did let the Nvidia installer generate my xorg.conf for me. All my
setups are Nvidia HDMI out -> receiver HDMI in. Then receiver HDMI out
-> tv HDMI in. That's all. How is your setup cabled? I've heard a
similar story before and it turned out to be a quirky receiver but I
can't say if NAD has that problem or not.
