Compared to the alternatives, take the 49 bucks!
As to SP3, it may be the old HP AMD issue (you can research that or hope someone tells you the fix.) That issue was widely discussed so I'm thinking your issue can't be that. Tell more and hope someone nails it.
I find many don't understand the OEM deal about support. Microsoft is not going to offer any support without a bit of cash. But folk seem to expect support where the OEM agreement tells us there is none. If you need more about this, we can discuss that too.
Reload OS, discs courtesy of HP, has update rollup2. Install all updates, install SP3, SP3 wipes out Media Center Edition 2005. Does this everytime I reload OS. Anyone have a fix, or know of this OS discs with XP MCE 2005 with SP3 on it? Called HP tech support, got India, could not understand tech's english. Oh, and they wanted to charge me $49, Microsoft no help either. This OS got dumped on by Microsoft, while working on Vista Media Center. Thanks for any help on this.Machine is HP Pavilion Media Center a1642x Desktop PC
