Download and install these in this order, and then reboot, run Windows Update
Then when you start Media Center it will automatically detect the tuners you have and the type they are and start the Freeviewscan. It will allocate all the channels correctly from the broadcast DVB-T, you don't need to choose a transmitter or anything.
So are you saying if you still run reliable XP then you've had it with media centre. Why weren't we warned. Just saying update to V7 is not good enough, they don't give it away and it won't run on my PC according to windows. This really is poor. I'm also confused ITV worked up to this morning now it's the only one on that MUX that doesn't. I've lost loads of over channels but can't understand why ITV 1 has gone
I'm on Win7 Ultimate x64 and I am at a loss to see why I've lost COM4 and COM6 at the 28th Sept re-tune. I'm still trouble shooting and will put my findings in here but it's looking like it might be in need of some patching, possibly the COM4/COM6 frequencies need updating within MC?
James: Some of the PC TV tuners use a "look-up" table of frequencies / UHF channels for tuning, to speed things up (corresponding to a particular transmitter). The look-up table can be edited, but a re-tune across all channels should find the missing MUXs.
It sounds like your PC may still be "remembering" the data for the MUXs prior to them being moved - I think I have to manually select all my channels and then delete all (involves right clicking in the "all channels" tab to discover the options "select ALL, delete, watch, details).
Once they're all gone, a full rescan gets it all back to normal.
Bob: By being located at less than 1 mile away from the Hastingstransmitter its possible that you are receiving an excessively high level of signal which is causing problems in the tuner.
To verify if this is the case if you have access to a set top aerial then for a test try that, or just connect a piece of wire about 12/18" long into the inner part of the aerial socket and re-scan using that, giving an update on results.
Had the same problem today with win 7 media centre.
Was fine over the first re-tune a few weeks ago but just went in today to re-tune after the second to find everything gone.
WMC couldn't find any tv signal (or so it claimed).
Tried it twice and nowt.
Re-booted and re-ran it and it was fine.
So suggest you keep trying.
Oddly, I also recalled some friends with a panasonic tv saying they had to run auto-tune on their tv 3 times before it found anything - I didn't believe them at the time :)
