Just caught this news (a couple of days old now) on xpmediacentre.com.au.

epgStream.net is a small group of coders based in Sydney who are putting together a free EPG solution for Australian users of Windows XP Media Center Edition. They're already supporting a bunch of capital cities, and it looks like regional centres are on their list too.

The product is really slick - you run a small installation program (which itself is ClickOnce deployed), and then set up MCE exactly the way you'd expect: Type in your postcode and let it do the rest.

If you're using XP MCE and you're looking for an EPG solution, definitely give these guys your support. Looks like they're looking for advertisers, too, so keep that in mind if you want some publicity and have a few bucks to throw their way.
