Hi Blade,
Thankyou very much for your reply, but my problem is not yet solved.
right after inserting the CD into the DVD drive , I am getting a error message like..
"While setting up DVD-Video playback, it was found that * Subpicture will not be available during playback"
and while opening a file in Realplayer , I am getting a error like
"Real Player needs to download new software to play this chip"
what I have to do now,I will be waiting for your reply
Kranthi.
