The patch adds a new configuration option to setup.conf, called "OnDemand"; it defaults to 0 (exactly the current behaviour). If set to 1, tuners will be appropriately opened and closed when switching channels. I've tested it with the vnsi plugin and XBMC.

Ciao Alberto,

Interesting work.  I live in the UK and have an HVR4000 for DVB-S.  Unfortunately DVB-T reception is poor where I live (hence the satellite solution - additional multilnb to point at 28.2E and 13.0E for L'Eridita) so I cannot fully test this past patching and compiling which I assume will work as you state you have tested.

Looking at the patch, there is something about inhibit epgscan.  I do not know much about vdr internals.  Would patching vdr and enabling the ondemand option stop epg from updating?  A slight negative if this is the case.


Ian.
