Just wondering, how are you planning to access video or TV from your iPhone, iTunes syncing or over the web?
If over the web:
I know my iPhone using Orb's web interface won't get video, and it's not even a Mac-based solution (Windows-only backend ATM).
I think the only Mac option I've found thus far is dot-tunes' plugin for iPhone. It streams only iTunes compatible formats, so you'd have to covert videos to MPEG4/h.264 first.
I haven't seen anything for live video/TV streaming for iPhone, and it would be nice to have. So, if you have found a usable solution, please share.
I'd be interested in hearing about xhub.
Here is the homepage for the developer of xhub, if you want to read some about it:http://www.snarb.tk/
xhub only works on OSX, it uses quicktime tools installed on and (I would imagine without major modifications) utilizes only local/network-accessible folders and iTunes/iPhoto libraries. That wouldn't really work for the home-to-work scenario you're wanting, since I doubt it would work with web-folders or something like .Mac.
I liked CyTV, and being an EyeTV Hybrid owner I understand its issues with CyTV (no analog live buffer). I would imagine CyTV works with the 250+, but it's fairly new and there isn't a lot of info about it yet. I would imagine for one the 250+ can't be in Game Mode for use by CyTV.
With the limited solutions available for your specific requirements (esp. regarding the iPhone), you might be better off using *nix or Windows for a backend, since those OSes have better options to stream TV and live video. There are some solutions for the Mac, but you might have to jump more hurdles to complete the task.
