i have a venue receiver with a VRT installed (all current firmware) when i go to 'Detect' on the venue i get a '?' on this channel. its not the frame, it follows this specific VRT module.. now i can assign it to be block 20, which it says it is on the VRT, but the frame cannot detect it. anyone know why this is?? could it be a VRS module which might have been tagged accidentally a VRT??
