No doubt your receiver is more sensitive to whatever has changed with CFTO HD. I remember back then in 2006 the Win XP PC based users that were using MCE were the most affected (similar issue between CFTO and WIVB I think , TSID related) but I cant find exactly what the issue with the MCE software was since the users on avsforum isolated the problem to MCE software and realized it was not dependant on tuner hardware or other softwares.

Interesting to see the outcome on this one and what CFTO might have to say. Too bad I lack the hardware/software needed to analize de PSIP data any further. It would have been interesting.
