DTVpal Converter Box digital "pass through" question
I have an early model RCA HD tv (720p) in a spare bedroom. This tv's built-in tuning and channel functions are very primitive, almost useless. The TV is only hooked up to a digital antenna, for OTA, and I get about 25 local channels. I also have a DTVpal digital-to-analog converter box, left over from use with my old analog tv. This converter box displays a REALLY NICE channel & program listing on-screen when used with a digital OTA antenna. The DTVpal device's channel & program guide displays on my RCA HD tv but, unfortunately, I have not been able to figure out a way to get or set the converter box to "pass through" the digital channels' video images WITHOUT converting them to analog images on my RCA HD tv, which look terrible (i.e., analog). Anybody know of a way to set a DTVpal converter box so it passes through the digital channel signals to the tv without conversion to analog images? I have the owner's manual for the device but it is moot on this point. Here's a photo of what the channel and program guide looked like on my old analog tv.
