[mythtv-users] Channel changing delays

[Tako Schotanus]

Ok, but I'd rather have some hick-ups in the first few seconds after a 
channel change than having to watch a frozen image and not knowing what 
is going on. Zapping around gets to be a bit of a nuisance that way.

I'm not saying I couldn't live with the current delay but _if_ there is 
a possibility to make it smaller.... :-)
