Ed,

Yes the Panasonic is a CRT (model CT-34WX52), and will reject 720p and 540p outright. So is there any way to get the DTC-100 to send standard (480 & 1080) resolutions only? If not, can I purchase a device that will do this for me (the Audio Authority 9A60 obviously does't)?

Short of that, maybe I should consider a different HDTV tuner. Any other more configurable units out there with VGA output?
