I have a mediapc HTPC with itunes content connected to my main TV and satellite box. I also have a pc connected to my bedroom TV.
I want the bedroom TV to be able to see and playback files from the HTPC. So far I have not succeeded in doing so. I also have a Intel mac laptop...it would be nice if I can playback files from the htpc on it but if that's too difficult I will settle for the bedroom pc.

1) How do I delete the poorly configured home networks I have created so far so I can do it again
2) Should I use mediapc to configure everything or some other software. So far it has been very frustrating.

3) Is it possible to view the livetv (via satellite) which is connected to the htpc from the bedroom pc. This is to avoid buying a slingbox or another satellite box for the bedroom.

I would appreciate any tips you guys can provide.

Thank you
