Streaming HD wirelessly

As I had mentioned in a preview post, I've been working on a mac mini MythTV frontend. The only current issue I have is streaming HD content over 802.11n. My first attempt worked great as long as I didn't move the mini to a different room than the router. I'm learning a bit more about wireless networking as I go along here, essentially, my 'old' router operates in the 2.4 Ghz range which is significantly more crowded than the 5 Ghz range, so I'm going to test out a 5Ghz router this weekend, and see what I can get.

Another possibility is to transcode the HD to SD (which is the quality I would be viewing it anyway) and stream that. I don't want to outright replace my HD content (I still watch it in HD downstairs afterall), so I might set up a User Job to transcode it, and place an entry in the MythTV database for a 'second' show.

I've been wrestling with the same issues.

HD over 802.11n 5Ghz seems to work a treat and I can highly recommend the NetGear WDNR3700 which has both 2.4Ghz and 5Ghz radios so you keep the 5Ghz (n) for your HD streams and use the 2.4Ghz (b/g/n) for everything else.

As for the transcoding thing, I've tried a couple of methods too, although primarily for viewing SD content across lower bandwidth networks.

1. Generate a lower defintion copy - but this takes CPU and disk space

2. Create a flash video transcode - same issues as above

So now I'm going to toy with VLC which should allow me to transcode on the fly to suite the available bandwidth without eating up disc but at the cost of CPU when a stream is running.
