Actually it seems that on Hybrid card is and will be quite common that multiple frontend share a single bus. Linuxtv API tell that a driver may offer frontendN nodes www.linuxtv.org/download/linux-dvb-api-1.0.0.pdf that vdr don't support I think is impossibile, to solve by driver, since switching between frontend happened by opening the frontend/demux device. VDR try access to frontend on start (actually it doesn't start multiple fe on same adapter, so I solved with symlink), and open all the frontend. If open fails it refuse to use the frontend. If open with success, it start N thread as many as the number of adapter/frontend. I don't understand what you mean for deficiency, if you mean the EBUSY, yes I could remove it, but it doesn't solve since with two tread open I should get a ping-pong between the two frontend so I can't get any image. If you mean for deficiency the two frontend on the same adapter, is logically correct, and is a deficiency that vdr doesn't supporti t. Since I like VDR, I'd like it support this.
