[QUOTE="jomed, post: 401248, member: 59882"] I just had an idea that could - in theory - reduce dvb channel changing times while zapping up or down considerably in situations with more than 1 available tuner cards. In short it would work like this (2 tuner example): Channel list: C1, C2, C3, C4,... 1. user watches C1 2. user hits Channel Up 3. tuner 1 tunes to C2, tuner 1 is shown 4. at the same time tuner 2 tunes to C3 5. user watches C2 for a few secs. 6. user hits Channel up again 7. tuner 2 is already tuned to C3 and display simply switches to it, which will most likely be faster then tuning in a new channel on the first tuner. 8. at the time tuner 1 tunes to C4 9. user watches C3 for a few secs. 10. user hits Channel up again 11. tuner 1 is already tuned to C4 and display simply switches to it. 12. at the time tuner 2 tunes to C5 13. user watches C4 for a few secs. 14. user hits Channel up again 15. tuner 2 is already tuned to C5 and display simply switches to it. and so on... Basically this would mean that the second (or in a mildly more complex scenario a third or fourth) tuner would be used to "pre-tune" the channel that the user most likely will zap to next. Since most people will watch a channel for at least 4-5 secs. before they zap to the next one, in theory this algorithm could deliver a more or less "analog" zapping experience for dvb-signals with next to zero delay.
