windows xp pro media center

windows xp Media Center Edition 2005
when you fast foward or rewind live or recorded tv it hangs and the only way
to continue the program is to lower or restore the screen or exit and go back
into the program.

i have tried all the trouble shoot and help files and even sent mail to
tech. and asked what to do. but so far i had no luck fixing the problem. i
even went as far to format the hard drive and clean install the windows xp
but the problem is still there.
is there anybody out there can help me?
