Just wanted to post this before I went to bed for the night.
I finally got the latest Mythtv and vmware workstation installed and working. Mythtv was a headache, the problems had nothing to do with sabayon or the build of Mythtv. There was a minor hiccup with vmware but again it had nothing to do with sabayon. That said, I'm set to dump 4.2 for 5.0.
Just wanted to say thanks and job well done to everyone involved with Sabayon.
