slight autorun

hey there is a problem with the autorun
when i insert a vcd (video compact disc) the autorun screen appears as normal, i click on windows player and it launch the only problem is that i recieve an error message. it tells that the file format is "." and is not supported, i take a look at the list pane and i see "g:" which is my drive letter. usually it should contain a list of video like "video track 1" and so on.
i run windows vista beta2 (i ordered the dvd) -- r.r
