Now for a side note:
I can tell you that Vista Ultimate works pretty well with the OML (Open Media Library) and Mymovies installed. With anydvd I can take just about any movie (currently my son's whole dvd Library) insert it into a dvd caddy, rip it to a drive, and mymovies then imports it. This works great on my main htpc in the basement but the client (currently a dma2200) is where I have the problems. With OML and bit os so-called tweaking I have the full library on my extender that I bought (only $120). VMC has some pitfalls but almost every place I have posted a question. Just my input. As for LinuxMCE it is currently only a test product in my house. I have new dinovo edge keyboard that I got for Christmas (bluetooth) that because it is bluetooth I was hoping LinuxMCE would recognize without tweaking...it didn't. I put the bluetooth dongle on my vista box and with no drivers, etc. it just worked. Did I pay for my VISTA (for those linux people that always push linux is free....) NO. It is a full MSDN version that was not being used from work.
I am still trying to decide if linuxMCE is for me but I don't have all the extra time to tweak, tweak, compile, modify this, modify that... maybe as it progresses it will get better!!
