To be honest, I get the feeling the digital-to-analog TVGOS feature was pulled after finding out it could impact sales of the TR-50. Personally, I know a lot of Sony HD DVR users who will latch onto a dual-tuner TR-50...especially if E* where to dump PSIP in favor of digital TVGOS.That I dont know but it could always be a feature of the TR50 which is a DVR and needs better guide data.
