Good luck, but it didn't take me more than 5mins to set up on my laptop and the netbook (once my desktop decided to play nice after fiddling with the network settings for ages!) Hopefully you should find it just as easy!
Well, about 2 hours ago it
was raining, so I dived in and downloaded XBMC on the PC & laptop, followed your instructions - as you say it wasn't difficult - and lo & behold, I can now watch recorded video off my Hummy. Brilliant! That'll do it me for now, no doubt I'll pick up other features in due course. Trouble is, I'm still experimenting with it, and the rain stopped an hour ago!
One thing that has amazed me is that the PC & Laptop can each watch the same recording, but each is able to start independently. ie if one person is 30mins into a film on the PC, a second person can start watching from the beginning on the laptop.... though at the moment I can't see how to syncronise them (ie have them both playing the same scene at the same time). The obvious idea of hitting the F/Fwd icon doesn't work as far as I can tell.
Also, when the two devices are receiving video at the same time, priodically each stops waiting for the broadcast to buffer; I don't think it does that when just one device is "on air". And when you pause a film, after about a minute, an error screen pops up and closes XBMC, so I have to start from the beginning again.
Otherwise, I'm very impressed so far. Thanks again!
