the motivation for this patch was to speed up zapping channels when using vdr-xine, i. e. to shorten the time from pressing the remote button till audio and video appear.
FF card users may only see the effect of this patch when the FF card is running in transfer mode.
Could this patch cause problems if vdr triggers a retune some time after the initial channel change? Perhaps this has to do with what UpdateChannels is set to at the time.
Best Regards.
