What the heck is this file format- .md?

I downloaded a vid from BT

The file format is .md0,md1,md2

So how do I join them together to watch?

Thanks!

those are image file......

need to have alcohol 120% or try poweriso, whether you can read them, it is a game file

So I d/l poweriso from download.com and take the usual steps?

Downloaded poweriso,tried extracting the file but error msg of the filename,directory name is incorrect

All files must be in the same folder.

I tried using alcohol,but have absolutely no idea how to use it

try magiciso, although alcohol 120% should work for most file types

I tried alcohol but totally lost…

Try daemon tools, though that tme it screwed my recording tab of cdrw.
