Visit
cd-2-dvd.com and you will find all the files you need.
You will need to register but it is free.
To find the Baldur's Gate autorun file, on cd-2-dvd.com, from the homepage use the 'Conversions' link (its in the top left hand corner of the homepage).
Then scroll down the list to 'Baldur's Gate and optional Tales of Sword Coast DVD *US Version*'. Then you will find the link to the autorun file.
P.S: I have fixed the Download link in the above conversion but it may not work unless you are registered with cd-2-dvd.com.
