Is XBMC for me? XBMC

tom

I have been looking at the Media Center scene for a qhile such as:
freevo, geexbox amp; mythtv.

I have installed mythtvbuntu on my server,  Its way too complex, slow and I gave up after 24hours of reading tutorials online.

Is XBMC for me?
- I have a spare server (high spec 3yrs ago, lol)
- I have quotinnacle PCTV Hybrid Proquot;

My Wish is:
- To request files/movies/tv to PS3 from Server.
- To use s-video (for now) to output server to MainTV
- To use PCTV (above) to watch, or record TV

Any help is much appreciated, xbmc seems great compared to the alternatives, except i see little/no mention of live streams.
