[vdr] HDMI output detection problems

since starting to use a AV receiver between TV and VDR, I have had HDMI 
detection problems.

To start X server even when TV is not on, I use custom edid file that I 
got from the tuner.  With this, VDR always starts X properly, so even if 
VDR has auto-started for recording, the output works.

Card: Nvidia GT220, vdr-xine plugin, Xorg, NAD receiver and Sony TV.

If I start TV, though, for some reason, most often there is no 
negoatiation (or a failed one) between the receiver and VDR, so there 
will be no picture.  Normally there is a sound, though. I have to switch 
the input selector of the receiver first to DVD input, then back to TV 
input to get the image.  If the tuner and TV are on when X server 
starts, the image appears correctly.

Are there any flags in nvidia-settings or Xorg.conf or Xine 
configuration that would tell the graphics card to help the tuner to 
notice that there indeed is an image also on the HDMI cable?
