Good, but only if guide data is available for *all* channels, otherwise 
calling up the EPG only to switch channels is too cumbersome.
Here in Italy guide data is only available for some state-wide 
broadcasters, all minor or regional ones are unlisted.
Surfing (or a local newspaper) is the only way to know what these 
stations are airing.
Big broadcasters have also DVB-T transmitters, while smaller ones are 
analog. My mythbox thus has two cards, with some channels (mostly 
without EPG data) only available on analog.
Being able to cycle over all channels would be a definite improvement, 
at least for me.
A related problem is card switching time. While channel switching is 
reasonably fast, changing card is hovering around ten seconds...
As many (most ?) mythtv users I'm using myth just as a super PVR, and 
only for the channels that have EPG data.
Otherwise, myth is almost unusable.
Don't get me wrong, I absolutely love myth, and use it almost 
continuously, but livetv is a bit undeveloped, imho.
