cluster software for video encoding

Hello All new to forum and fairly new to linux.
What I would like to know is, is about clustering. I have googled My tail off and have not found the answer. A little about My linux knowladge I have been using mint on one of My pc's for a few months, the rest are xp I have 6 pc's mostley old stuff 1.5 ghz or less half stay on for various reasons ie 1 is in a mame cab, 1 is httpc in bedroom, etc.

The question is I would like to make a cluster out of them for video encoding dvd to .avi and .avi to dvd I have read about a tone of stuff for e-mail servers, load balancing, sql servers etc. The only thing I get out of this is the only thing a cluster is good for is servers or data base's. I know this has to bee wrong. I have 0/no programing skills,
so can Somebody PLEASE point Me to a good source for apps for clusters other than admin utils. or at least a papper other than the dozzen or so rehashed ones that google brings up?
What I would like to know is ther software that runs on a cluster out of the box, so to speeck, other than admin utils or does it need to be writen for a cluster?

Please forgive a noob for such a simple question.

You could run them all as a cluster to encode video, for example check out the dvd::rip cluster mode, but the real world performance will probably be significantly less than what you are expecting.

People tend to assume that a cluster is capable of incredible feats of processing, but this is really only the case in select applications and hardware configurations. Cobbling together a bunch of outdated systems (mismatched, at that), combined with the physical and software overhead entailed, means you will have a big complicated system that almost certainly won't be any faster than even the cheapest quad-core CPU on the market.

However the bigger problem is, as you said, all of those machines are already doing something in your network. You would need to have them all running Linux for this to work, which sounds like it is going to be a problem. Unless you had a setup to PXE boot them into a minimal system, but even then the machines won't be available for their intended uses (hope you don't want to watch anything on the HTPC while encoding videos).
