Howdy. I'm a MythTV user since August of 2004, with version 0.15. My MythTV setup consists of a Shuttle SN41G2V2 Small Form Factor box as backend and frontend, with a Hauppauge PVR-350 and the included Grey remote, and have the card linked via S-Video connections out to my TV and in from my Dish Network satillite box. The box is powered by an Athlon AMD 1600 MP (yes, an MP), which has been powerful enough for this purpose, when combined with the PVR-350. I use Gentoo, which has generally made package management very easy for this project, with very high uptimes. I have 350 GB of storage, using LVM, with a storage volume concatenated across two Seagate Barracuda PATA IDE drives (very quiet drives). I use MythStreamTV to stream shows ala Slingbox (but have been doing it since before Slingbox existed ;) ).
MythTV: 0.18 MythStreamTV: 0.96 Kernel: gentoo-sources-2.6.16-r9 (recent upgrade from 2.6.15) ivtv: 0.6.3 (recent upgrade from 0.4.5)
Thanks for the better TV! :)
