@ Lucero
Thanks for the suggestions, I'll put them in the OP now.
@ BunnyKillBot (nice name btw)
I agree that WMC is underrated somewhat as it is hit with the M$ tarnishing brush as with most of their software. However, it's not without its problems. Although simple to use it lacks flexibility, and having the 'just works' ethic it also is limited in terms of really good 3rd party add-ons and new features being added. There are a few things I'd love to see that'd make it perfect:
1) Proper blu-ray integration. I don't care if you have to buy Power DVD or something, but have it built in from the start and maybe unlocked when you do.
2) Proper itegration of popular UK on-demand TV services. The above plugins work, but are limited. There is MSN video integrated now, so no reason why there can't be more (technically that is).
3) Updated interface. The current one is too big, almost like it's for those with sight impairments. I'd like more rows and columns on the EPG, and updated menu images etc as those and the low res backgrounds etc don't cut it today, they just look dated.
Edit: Updated OP with 3 new programs and changed colours a little for clarity.
