step by step video guide for DRM convert

[CrayDeng]

Hi, everyone.
I found this step by step DRM demo on youtube, refers to a product called Digital Media Converter . I think it should be used for some downloading softwares which have DRM technology like Napster, Rhapsody, limewire, iTune, bearshare....... .
And if any ideas about the DRM or the relevant softwares please feel free to post it below.
I need some info.
thx.
