Creating Music Playlist Files on the HUMAX HDR7500T 1TB

[Dwarfboysim]

Hi all,
I have read in reviews that the Humax HDR7500T 1TB should support Music playlists.  Can anyone confirm this and tell me what format the file needs to be eg: file extension and the best way of creating them.  I have tried speaking to Humax Tech Support and I keep getting a response about what format files it can play.

Any help would be appreciated as I have a substantial MP3 collection and having to individually select files each time is a pain.

Thanks,
