Sorry if this is in poor form, but new to the forum (pardon the pun). Just wondering if there are any other MythTV users/former MythTV users out there, or anyone else with a DIY DVR? I've always loved DIY DVRs because of how much you can do with them. Custom UIs, access to the Internet (for NetFlix, listing data, weather, news, video data, web radio, etc), and the extensible nature of the hardware (how many off-the-shelf DVRs do you know of with more than two tuners in them?), it seems like more than an excellent trade-off for the complexity and investment of time. For anyone who doesn't know, MythTV is Linux-based DVR software. It consists of two parts, the front-end and the back-end, where the front-end handles playback and the back-end handles recording, commercial flagging, media management, etc. They don't need to be on the same machine, and there can be multiple back-ends and front-ends all working together. The capabilities of a MythTV system tend to be limited by the hardware (you can only pack so many tuners into a single machine, but you can always add more machines). Also, while listing data used to be free, it's now $20/year in the US through Schedules Direct. Still cheaper than TiVo. My current (inactive) MythTV machine is a Celeron 600 I picked up six or so years ago, with a Hauppauge PVR-150 for recording analog cable, but now I want to retrofit it to receive OTA HD with the HVR-950Q I have (I'll need a USB 2.0 board for the machine to make this happen) and get FTA satellite transmissions (I'll need a whole mess 'o hardware for that). Since the PVR-150 has a built-in MPEG-2 encoder, and OTA/FTA transmissions are already MPEG-2 TS, all I have to worry about on this system is bus speed (getting enough data to the HDD fast enough) and RAM. Using the automated commercial flagging will probably be a big no-no on anything in HD, since the thing was slow enough with Standard definition material. I've considered playing around with Windows Media Center, but I'm not a huge Windows fan, and it seems like I'd lose a mess of features with MCE over MythTV (like separated front/back-ends, hardware support, slave back-ends, auto-commercial flagging, auto-transcoding with RSS feeds, etc) so I'm very reluctant to put any money into it. Still, if any of my concerns are "mythical," please feel free to correct me.
