Ok - I think you really need to understand some aspects of web development before you undertake these "projects".
I have had a look at this ASP object and indeed it does let you access the CD drive ON THE SERVER. Asp, PHP etc all run on the server side machine and produce static web output to the user (made dynamic via various scripts such as Javascript, VB Script etc). There is no way for this object to be used to access a users CD Drive on the other end of the web browser. This goes for all languages I can think of including PHP.
Just so I don't just sound like someone putting you down and being unhelpful - there is a solution/workaround to this problem. Unfortunately it requires one of two things. Either a plug-in for the user which they have to download from the web, or a custom written Browser.
If my memory serves me correctly, this has been done with DVD's (and maybe some CD's) by both of these methods.
As to where to look for this - I think (I'm sorry of this is wrong) - PC Friendly was a browser which allowed this at one time - more or less a cut down version of a browser so you would probably be limited to the sites functionality. Alternatively try looking at www.starwars.com - they may have some info about the plugin version since they made up of this technology with Episode 1.
Ultimately - this is not an easy thing to achieve, the scripting required can be quite tricky (for the plugin anyhow).... not a project you want to underatake if you don't really understand the technology in the first place.
