Another re-install?

To solve several problems with MediaPortal, I decided to upgrade to an SVN version (untested development snapshots). I had been waiting for version 1.0.1 of MediaPortal to be released, but the deadline of 15th March has been postponed with no ETA...

The version I upgraded my MP 1.0.0.0 was this one 02-10-2009 Rev:21688. This version fixed:
(a) the unsupported skin message at MP start-up, and (b) I can ESCape out of the Recorded TV screen. Unfortunately, when I installed this SVN version, I did not perform a complete uninstall of MP. And last night's installation of my new GPU (more below) there were problem not being able to make certain configuration changes that would 'stick'. I think I will have to wipe MP 1.0.0.0 completely off the system, then install the latest SVN version: 03-22-2009 Rev:22029.

I spent a few hours last night installing and configuring my new HiS 2600 HD GPU, to see if I could get BBC HD/ITV HD broadcasts decoding properly on my P4 HTPC within MP. I had varying success, the card certainly produced good enough pictures to watch, but they were not smooth enough. I also had problems with MP crashing out and freezing up after a while of watching BBC HD, but I haven't be able to isolate the problem. I am considering a re-install of XP to get a clean system install to see if this helps... but this does mean investing more time and effort.
