[QUOTE="htpcoz, post: 124542, member: 13987"] Taipan, thanks for the look, I had looked at individual instances of these, but hadn't noticed there were multiple occurrences of these for some of the channel changes (which is why the individual 5 second occurrences add up to the big delays). I've downloaded ScanChannelBDA to get some statistics on signal strength, and interestingly, the values are all over the place, the signal quality usually locks on to 100 pretty quickly, but signal strength reports values like 80000, and -6300. So it looks to me like the dvico BDA driver is reporting garbage in the signal strength, which I guess is resulting in MP believing it doesn't have a tuner lock, and causing these delays (strangely the scanchannelsbda never seems to get a "real" value for strength, so I wonder how MP eventually gets a lock). I've got the latest DVICO drivers (unless someone knows of more recent ones... but these are the most recent ones I could find on the site). I looked into older ones, but unfortunately only the most recent ones actually support the new Dual Digital 4 card. Not sure what the best path forward is here, I guess my read on it would be for anyone thinking about the Dual 4, (in aus anyhow) might be best to steer clear for the moment. TVEngine 3 does actually seem to perform a bit better, but it is very limited in many respects for the moment, so I've had to move back to the old engine, and the slow channel changes. [/QUOTE]
