[mythtv-users] Request for help making live TV useable

I've been using mythtv since around version 0.12 and have never found the live tv function to be terribly useable.  For me there have always been lots of crashes and it seems to have only gotten worse.

While I've watched some new functionality like the internal video player go from alpha quality to being a wonderful solidly mature feature, live TV for me is still problematical.

I currently have two sets of capture devices:
  a pair of NTSC plextor convertx usb2 external capture units w/ mpeg4 encoding
  a pair of HDHomeRun ATSC ethernet external capture units each with a pair of ATSC tuners.

They all work very well for recording.

LiveTV has always had problems tuning.  95% of the time it would crash after a channel change. 

For liveTV, version 0.23 got bad and 0.24 has gotten worse.  I can no longer switch channels at all.

I'd appreciate any suggestions on how to debug my setup.  I'd rather not completely erase my capture cards, as it'll cause all my recordings to no longer display what channel they were recorded from.  However, if I have to, then I will.
