I am compiling libsoftmpeg and the softmpeg plugin from linuxtv.org.
From the low-activity mailing-list, it seems that there is at least 
experimental support for the HW decoder.
But the plugin is for VDR 1.3.x, and I currently use 1.2.6... Don't know 
if I will go very far yet.

I can now reproduce the behaviour : I always see the same blue screen 
without cursor, no crash but no video and no OSD. VDR logs are quite 
normal, and SVDRP comands are executed.
I think it is a matter of some tweaking in the parameters of the 
frame-buffer (pixel layout, video overlay, screen size...) I tried to 
change some things in the video_dfb.c code, but I don't know where to 
start and what information could help defining the right values.

In fact, I actually saw the OSD using directFB on sunday evening, but I 
can't reproduce... I remember that the video capabilities reported by 
softdevice about the CLE266 where quite weak, just as if the frame 
buffer was vesafb, not viafb. But /var/log/message says I had just 
loaded the viafb module before it worked... Maybe I had a strange mix of 
vesafb compiled in the kernel and viafb compiled as a module, both 
loaded in memory...

I'll go that way if I can't make the framebuffer work correctly.

Thanks,
