You mean: mythbackend --verbose important,general,eit
It's just a list of logging 'subsystems' to turn on. 'general' is the  
standard day-to-day stuff, 'important' is probably a subset of that. 'eit'  
turns on the extra eit logging

There should be a key binding for going up/down channels - up-arrow,  
PageUp ?
You should also be able to just type numbers in for a specific channel.

I'm not surprised you have trouble then. Those cheap antennas are rubbish.  
And amplifiers often cause more trouble than good.

Excellent! I presume it's not going outside...

A few years back I diagnosed my reception issues with some precision  
German engineering (ie. electric cable & a ruler): The Google translation  
isn't great but:

Not sure whether its suitable for your US frequencies but it's simple and  
very impressive - it performed as well as my roof-mounted log-periodic.  
And if it's inside, taping it to a window is an effective trick.

Note you shouldn't put aerials 'in parallel' though - they interfere with  
each other and splitters/connectors etc are often the source of your  
problem. Use the shortest piece of good quality co-ax & put it straight  
into the tuner is the best advice.

I haven't noticed your other thread but that sounds more like reception  
issues to me. I'm not sure a cpu can be 'too slow' for myth these days. If  
it can play a recording or video ok then live TV should work the same,  
*provided* you have a good signal. Have you tried pausing it for 10 secs ?  
There is a known feature that playing Live TV too close to real time can  
cause it to stutter.

I recommend you sort out your reception issues before shelling out on new  
hardware.

Good Luck!
