Whenever I include media player as a reference in VB it is using Media Player 6.4. Which is the proper OCX file I need to include to get access to Media Player 7 or 7.1?

The main reason is I want to access Media Player's built in ASX parser to read and write playlists for a custom MP3 player. Does 6.4 have an interface for me to write ASX files? Or do I have to go with 7?

Thanks for help in advance!
