It seems that the guys over at EngadgetHD have unearthed some annoying information: the Zune HD will not support 100% of the media that Windows Media Center does.

Specifically, HDTV and DVR-MS style media recorded with Windows Media Center will not work on the Zune HD’s Zune 4.0 software.

Sure, you can convert these files but how nice would it be to throw down HDTV records onto your Zune and then plug it right into your HDTV for some easy streaming? Common, Microsoft, hook us up!
