just finally got my myth boxes working. It is a nightmare on the setup side, mysql was running on the slave backend with xbmc! many a night pulling my hair out !!!
However it has been worth it, I wanted a box to do all ie music,Films,live tv and pvr, to replace dm500 * 4 and a Dm7020, I wanted to be able too share all the media content from one box, which I now have and the hd channels bbc and itv chan4.
At the minute i have my server (mythbackendmaster) with a dual pci card in it which will take care of all the media files and pvr, I have a 80gig sys disk, then i fitted 1.5tb for media ie films,music and a 1tb for tv pvr, I also have a slave backend with 2 pci cards in it the lounge(waiting for the cable too come too mount a new dish) also running a small revo pc in the bedroom as a frontend, the dm7020 is in use for a cccam server for my card which now works with mythtv, i will be removing this in the near future and using a card reader on the server, I couldn't be more happier (still a few glitches), need to get the trans-coding to work and auto remove adverts, also how many satellite feeds i will need to serve the rooms ie kids bedrooms etc... It would have worked out cheaper than buying the dreamboxes and is more future proof..
