Is it really an existing frontend that you want to use - or an existing backend?
Whoops, sorry - I made a typo in my message two messages above. What I meant is that I'd love to be able to configure LinuxMCE to use my existing *backend*, which has been stable for years. The assumption today is that you'll use the mythbackend on the core.
From what I can see, there would also not be too many major issues with using an existing backend from linuxMCE as well (as long as versions matched etc) as the only really tie in that I can see between linuxMCE and MythTV is done on the MediaDirector and the shared file system.
Right. I got a media director to use my existing backend. I don't remember exactly what I did but it may have required CLI access, which is not a big deal. I just wish LinuxMCE played a bit better with things you may have running already, like MythTV and Asterisk.
Personally, I think that relying on any specific distribution is not the best way. For example, I run MythTV on Debian. It's nice that the MythTV software doesn't force me to run Fedora, or Ubuntu, or anything. I look forward to the day when I can do "apt-get install linuxmce" on my Debian box and get a working LinuxMCE installation without having to install another distribution, and without having to use versions of Asterisk or MythTV that have been tied to a specific LinuxMCE version. I hope this day comes one day :-)
