I took delivery of a new HDTV this week and up till then, when my HR20-700 was installed, I turned the "native" mode to on so it would match each channel's broadcast to the TV. I found the HR20-700's native mode to work much better than the HR10-250, where I always had to press press "full/panel" to change the image. Upon getting my new HDVT, when I tune to certain channels, like CNN or FOX News, for example, my TV screen goes black with a message that says "mode not supported." If I turn off the native mode option, then I can view these channels, but then I'm forced to manually select "format" on my HR20-700's remote to fit it to the screen, etc. Has anyone else had this problem? (Again, it only happens on a select number of channels.) I sure liked having the HR20-700 in native mode, but unless there's something I'm missing here, I'll be forced to have its native mode turned off.
