The Zune software purportedly supports wtv and dvr-ms files, both in SD and HD video formats. HOWEVER: the Zune software, in Microsoft's infinite wisdom, does not support decoding of the Dolby Digital audio format that ATSC TV uses. This is despite the fact that Windows 7 includes a Dolby Digital decoder for Media Center. Prior to Zune version 4.0, TV content would show up in the Zune software, and you could sync the video, but no audio would transfer. Supposedly, stereo HD or SD will show up and sync, but as there is almost none of that content available over ATSC or QAM it is of little use. So, theoretically, yes the Zune supports Recorded TV, realitstically, no.
