Hi I have a Vaio LT1S,
I have just upgraded from vista home prem to win 7 home prem
Now it wont play blu ray ,dvd or live tv
Win media centre wont play dvd or tv
Windvdbd for vaio wont play blu ray
I have just checked my window experience score and the graphics memory is not dtected,the graphics scre is 1.0!
Everything worked before the upgrade.
maybe the best upgrade would be to an IMAC!
Have you tried the obvious and tried reinstalling the Video Driver? Some nVidia drivers will not pass the upgrade test.
You can find the original driver in the list here: -

Or - perhaps a better move - install a more up to date driver here: -
http://www.laptopvideo2go.com/drivers/vista/176.37
Only the version 176.37 will install on your Vaio - don't try any others from the site unless you are familiar with modifying .inf files.
Come back if this does not work.

hi thanks for that,i have tried but i get this message ,

Are you using internet explorer 5?
It looks like the file may not have downloaded properly.
I would save it to a specific location like 'Desktop' and try running again.
Ok tried that download open file
application not found
I have just downloaded it using Firefox browser.
The file is a zip file which needs to be openened with winrar, winzip etc.
The extracted folder contained lots of files...I selected setup.exe and it
started to run the application fine.
Try right clicking the zip file and see what the options are for extracting the folder
from the zip file. 
Yey all fixed
downloaded with safari unzipped ,as suggested by you kind people,opened exe
run,restart,resolution back to full.
now i can play blu ray and video and tv.
Thanks to every one for there help
Excellent
Glad its sorted.
