PS: i might improve soon to add more funtions from CD ROM class but at the moment i have done only the required part based on a query posted in the forum...

hmm, sorry , forgot to mention this , i havent found the complete documentation on understanding the drive capapbilites, e.g., mine says removable media and random access. it supports cd writing not dvd wrtigin. i am working on imapi objects information collector and will soon post something in that direction which is much more reliable comparing to this...

<Again!!!, found IMAPI2 interface has been ported already, atleast didnt waste time working on it, i just had checked the forums before spending more time... :-) >
