OK, Jarod's point is well taken -why distro-hop?

All the reasons I went with Mythdora in the first place are still  
there - out-of-the-box support for my hardware (Fusion HDTV - not the  
MCE edition), even the wireless card is detected, I just can't get it  
to join my WPA2 network, plus a sensible fs layout - I'm not a fan of  
long-term storage under /var myself - and a decent mythtv user etc  
etc ...

So, onto the next questions:

I currently have a PATA-based system, my new one is going to be SATA -  
so I need to move everything across.
The mythtv-wiki gives instructions on how to move the database across,  
and I can just copy the /storage across to a new drive, but is there  
any way to get all my settings, channel ids, shepherd configs (I'm in  
Australia) and the like across?
