I think it is a combination of DVB channel change time, plus the relatively long period of time it takes myth to buffer up some stuff and get going. (Personally I think it is too slow for livetv viewing as it stands though. Something like 3-4 secs to change channel. Makes a good video recorder though)

No, something very much like Kenneth had included in his last patch he
sent to me, where he just checked, if the mux between old and new
channel matches, and if so, didn't tune (the real tuning, not PIDs) at
all. PIDs are handled differently, so it's easy to still change them.
Unless I miss something.
>What is your "dvb status" btw? Are you still waiting on your building to add cabling, etc?
I have permission from the house owner to set up a sat dish on the roof,
but no cabling. WLAN (roof to my room) worked, but I didn't test speed,
and now it doesn't work anymore again. (Hardware setup under Linux is an
unacceptable pain! at least with the distros I tried.) I have a offer
from a TV technician to set up the dish (has to be professionally
mounted, with hole in the roof and all) at 400 Eur for the dish setup,
all in all. Considering that and that
- I have to buy the DVB cards, potentially a computer for the roof
- I have to spend time to set it all up
- I don't have time to watch TV at the moment anyways
- I'll probably move out of here within the next 6-12 months,
I decided that I'd rather spend my time and money otherwise, at least at
I'll definitely go for DVB after I moved.
