[vdr] fbxine display falls asleep???

[Hu-Emulator]

This a follow-up to a earlier email. I was asking before when running fbxine 
that after about 10-15 minutes I get a black screen but still hear the audio 
and can change channels with the remote but with no OSD. And at that point I 
would just stop vdr and then restart for another 10-15 minutes. After the 
3rd time it would be stable and not happen. Well so I was thinking if its a 
display issue and not vdr. So I rebooted and restarted fbxine and vdr. This 
time after 10-15 minutes and the screen went black and the audio was still 
working; I hit any key on my keyboard (remember display is out to tv) and 
wholla the video came back. However it would continue to go out after like 
10-15 minutes. No matter how many times I had to just press a key on the 
keyboard. So its acting like the display is going in (screen saver mode)? 
How do I stop that when I am not using Xwindows but using fbxine?
