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.
But i do notice some issues with you install/list of parts.
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.
Also an Athlong 2000+ pry wont handle HDTV/DT shows. Plan on atleast
3.ghzthe 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.
