We've finally got MythTV up and running properly. I have a fanless Via EPIA system sitting on top of the telly as the front-end running MiniMyth. It's very very nice!
I had trouble getting my existing, serial remote receiver going with MiniMyth. It wasn't made any easier by being so difficult to debug on that platform, and my laptop not having serial connectors. So I ended buying a known working remote with the config files found here.
Still to get working is mounting my music and other video on the front-end using Samba or NFS. Also need to plug in the new DVB card I bought last night, which will involve some shuffling around of cards in the server. And I need to buy a SATA interface card to connect the 600GB of disks that Moz has for me.
So far, with only one tuner and 16GB of disk space, I'm very very happy with it! I just wish Australian TV was better at sticking to their bloody schedules. With more than one tuner, I can set it up to record five minutes either side, but I shouldn't have to.
