After loads of mucking around with my HA51 AVPC, and some regular crashes, i decided I knew exact;y how I wanted the machine, and would reformat, and do it from scratch with the recovery DVD and the driver CD.
Well... the recovery CD is merely WinXP Media Centre edition - not a full recovery image. Once installed (and it had loads of trouble with the SATA driver), I had to install all the drivers from the driver CD.
Boots up, media centre runs fine, tv tuner driver installed, but when trying to access live tv (or indeed any incoming video stream e.g. sky), it says "video decoder malfunctioning or not installed, please restart media center or your pc".
Any tips? Im going nuts here, and dont want to hav to send the entire thing back to DSE to have them copy an image over from a new machine.
I guess i should have taken an image on day 1 - but with a 'recovery DVD' i didnt really think it was necessary :-(
