[...] Any chance of using using DVB-T frontend on HVR-4000? This card have 2 separate frontends. And as quoted on http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-4000:
"Multiple frontends are supported: DVB-S/S2 and DVB-T appear as /dev/dvb/adapterN/frontend0 and /dev/dvb/adapterN/frontend1 respectively.
Due to a hardware limitation, the two frontends cannot be used simultaneously. However they can be used sequentially within the same application. The driver handles the mutual exclusion appropriately."
Well, that's still a problem. Is there a defined way (via the LinuxDVB driver API) through which VDR can find out whether the frontends can be used independently?
Shouldn't all frontends that are independent show up as completely different adapters in /dev/dvb/, so that VDR can assume only one frontend per adapter is usable simultaneously?
I would love it if I could assume that with an adapter with several frontends, only *one* of these frontends could be used at any given time, and that, if a DVB hardware provides several frontends that can be used simultaneously, these would appear as separate adapters with one frontend each. That would be a simple, straightforward setup. But apparently things aren't meant to be simple... :-(
