Slow channel change

[onelegend]

Hi there

I currently have 3 machines each with TBS6981 tuners.

Software, DVBLogic TVsource 4.0.1:
I'm having problems with channel change times - it takes about 11 seconds to lock in on the first channel, about 6-8 when changing channels there after.

I must say, I downloaded DVBViewer - I have more then acceptable channel change times with that software (about 0.5 seconds), however this doesn't integrate into Win 7 Media Center.

I believe media center will be accountable for some of the above delay, but looking into the logs of DVBLogic TVsource, the channel lock is taking 4 seconds minimum, reducing that will make a big difference!

Log text from TVSource (4 seconds):

2011-Nov-26 14:54:18: [I] Status: Locked

This occurs on all 3 machines, different system specs for each.

I have tried the latest driver of course - 2.0.1.1

Hope you can help

Many Thanks
