I have DTC-100 and Mitsubishi WS65903 HDTV, with VGA to BNC-HV adapters for high definition signal.
1) Using the regular ANTENNA without activating HD MONITOR button in the front panel, all Channels work fine but they were not HD signal.
2) If HD MONITOR button in the front panel is activated, the TV screen goes blank!!!
**Questions: is it the ANTENNA? (I have a big good one on the roof)or is it the VGA to BNC-HV adapter? or are there any settings inside the TV or DTC-100 that need to be set? or are the two units not compatable? Please help!
***Anyway, all digital channels are about a little better than the picture from the cable but for sure it's not HD!!!

Thank you,

Antoine Vu
