<div>Slave backends are basically a full blown backend except they share the database from the main backend. This allows you to add more tuners to the entire system. It works quite well.</div>
<div> </div>
<div>But i do notice some issues with you install/list of parts. </div>
<div> </div>
<div>The backend you described with the 1.8ghz will be fine for hardware encoding cards and digital TV recording. But putting a frame grabber on the system is going to really tax it if its doing other things such as commflagger, transcoding or recording multiple shows. I dont understand why you really want this? I am not familar with this Adaptec card but before you buy make sure it is supported on linux. The PVR-150,350,500 are by far the most common tuners and therefor have much more support.
</div>
<div> </div>
<div>Also an Athlong 2000+ pry wont handle HDTV/DT shows. Plan on atleast 3.ghz the more the better. You may get by with the 2000+ if you use XvMC with a Nvidia card but it may have some frame bufer problems.</div>

<br><br>In the next couple of days I am having a satellite dish with Quad LNB<br>and new digital aerial installed. Now I have been planning on setting<br>up a MythTV box to record from digital free to air satellite and digital
<br>terrestrial TV.<br><br>My original idea was to have a combined front end and back end to handle<br>recording and playback. I was also hoping to fit an Adaptec PCI MPEG2<br>encoder card (same sort of thing as the Hauppage PVR-250 I think) and
<br>also a standard BT878 TV capture card to handle capture from video (to<br>transfer all those old video tapes to DVD).<br><br>To run all this I was thinking of using an Athlon 64 3000+ with a Serial<br>ATA hard drive, 512MB (or possibly 1GB) memory under Ubuntu
7.04 (when<br>it is released).<br><br>On reading through the Ubuntu Edgy MythTV documentation noticed it<br>mentions slave back ends. This got me thinking, would it be possible to<br>have a main back end system based on something a bit lower spec like a
<br>Pentium 4 1.8GHz, 512MB memory and the DVB-T and DVB-S cards to live TV<br>and scheduled recording and then have a combined front end/slave back<br>end system downstairs plugged into the main TV based on something like
<br>an Athlon XP 2000+ with 512MB memory to playback recordings, view live<br>TV and also record/view video from the MPEG2 encoder card and BT878 TV card?<br><br>Is anyone else using multiple back ends with one (or many) front ends?
