Thanks for the advice Colin, I thought that I read that it was mythtv-setup
that did the schema upgrade, this has always been my practice. It saves
editing my .xinitrc each time to start mythtv-setup instead of
mythwelcome... cool ;)

Thanks again, I don't think it should be a problem for me though. I have
never installed mythtv from portage, I have only ever compiled mythtv from
source and have always used /usr/local as the install prefix. Although I now
understand why compiling plugins can be a big problem if another install
