Hi again,
another day, another vista problem.

this time media centre, i got to say, its the Best ,most user friendly program i have used on a PC.

Even my wife can use it!

my JUST 8 y/o can play shows, skip 'adds' and find her movies!

But 2 weeks ago a 'new' error started....

basically i narrowed it down to: when recording a show(HD seems worse) and 'timeshifting',that is watching it later,skipping adds and catching up,after some 10 to 20mins of viewing i get a MASSIVE FREEZE,im talking 1 second sound echo and picture freeze(still) and NOTHING WORKS,cont/alt/del, Only OFF button for 7 seconds...

i asked computer shop guy, i did all the followingbasically everything)

*checked vista update,done all recomended(just a critical update)
*removed some 125 gigs shows from C drive 403gig HDD to my backup 403gig HDD.
*went to nvidia, and got it to update automatically my motherboard and graphics card(vista version was older, loaded 6 weeks ago!)
*went to haigpagen twin HD TV site in australia, and updated driver.
*Defraged C drive.
*scanned for virus with AVG7.5.

pc was a bit faster, picture actually looked a bit clearer(maybe just me),but still timeshifting error(only once though so far). i stoped all family from timeshifting Now. pain in the rear!
