If you have the most up to date version of Windows Media Centre, in Windows 7, and use it to watch Freeview with whatever DVB hardware you may have inside your computer, and find that following retuning on or after 18th April, you no longer have any channels at all, please post here. Of particurlar interest is if you are inside the Crystal Palace transmitter region.
Note that the hardware you use must be solely using the Windows Media Centre and not the manufacturers own software.

I could never get WMC to work with my built-in TV tuner in my MCPC so I installed some free tuner packages, AVS TV Box & MediaPortal.
I don't use it often but 2 years ago I could tune OK to Hannington (South area). More recently I cannot get any digital stations; I guess since South area went digital. Though I could get the London area analogue stations which disappeared completely on April 18th.
Now I cannot tune to neither Hannington nor Crystal Palace transmitters using an indoor aerial (my house TVs are tuned to Crystal Palace using an outdoor aerial). So I've given up using the PC's TV tuner and just use the online TV Catch-up services.

I have three Win7 Media Centre PCs, and live a couple of miles from the Crystal Palace transmitter. All PCs retuned fine on 4th. April, but none have functioned since 18th. April. When attempting to find channels, I just get the spinning "busy" circle, and Media Center hangs, and can only be stopped with the Task Manager. I have reported this to Microsoft at https://connect.microsoft.com/site1145/feedback/deta... and would strongly urge anyone else with this problem also to record it at the Microsoft Connect website. kleh.

Doubt it is WMC software. Am getting same issues with other tuner software. More likely it's the TV tuners themselves.

Some old FreeView boxes don't work with the new channels because they can't receive the frequencies used. It's quite possible that the same is true for older computer cards.

I have tuners from four different manufacturers,. I think it is too much of a coincidence that they are all having an identical problem.
|
|
|
|
One of my tuners is in a PC which is less than one month old, so age is very unlikely to be the problem. I have submitted a support call to the manufacturer.

How many different chipsets are in there?

You've given me an idea 
Just notice that the muliplexes' channels have changed pre- & post- switch-over: - Crystal Palace: From 22, 25, 28, 29, 32, 34 to 22, 23, 25, 26, 28, 30
- Hannington: From 40, 41, 43, 44, 46, 50 to 39, 41, 43, 44, 45, 47
and I think some the frequencies within them may have changed slightly.
So I now think that the problem is with the pre-set data held within these software packages that define the channels. I know where this is with my installed tuner packages so I'm going to play with those. I don't know where this is held for WMC.

At least two different chipsets.
One of the tuners is for DVB-T2.

It's not held locally on the PC, it's stored and updated online by data providers working on behalf of Microsoft. Microsoft maintains a website where you can comment on the accuracy of this data (at https://connect.microsoft.com/site1145), which I referred to in my intial post. I posted there on 18/04 questioning whether the London data had been correctly updated after switchover. Microsoft confessed "We have been informed by our data providers that there was a temporary delay in data upload, but this should be correct tomorrow." As far as I can see, the mappings have still not been updated, and I am pretty certain that it is this, rather than Media Center software or tuner hardware which is causing the problem. If you google "Digital Switchover" you will see that exactly the same thing happened in the USA in 2009, and people were unable to use Media Center for weeks.

Are you replying to me about the location of the tuning data for WMC? (at https://connect.microsoft.com/site1145 ), Both your links to MS don't compute cuz you need spaces around URLs; corrected above.

Yes, that was info about the location of the tuning data

And what was your link meant to be in your post: http://forums.thinkbroadband.com/windows/t/4116558-r... ? Even with space it does not compute. Spell it out.

Not that one but the one that looks like: https://connect.microsoft.com/site1145/feedback/deta... ?
Of course it looks fine to you; you put a newline after it. Have you ever tried clicking on your own links?

Right, the tuning data, channels & slight frequency shifts, has changed since the switch-overs on all regions and it doesn't look as WMC has caught up.
I've changed the preset tuning data on my 2 TV tuner packages. However, on Hannington transmitter, I can only tune 2 multiplexes out of 5 (the 6th is HD only) and get about 52 stations out of 114. I shall continue experimenting to try and get the other multiplexes.
I also found that my previous indoor aerial position is useless and I'm having trouble finding a suitable position. So maybe signal strength has reduced.

I am getting much better reception now on both my Freeview box and a media centre with Freeview built in. Both are using indoor aerials.

Everything worked here in SE1 using Hauppage Nove TD 500 (DVB-T) and BlackGold BGT 3620 (DVB-T/T2) dual tuners. I did a complete rescan, not a scan for additional channels procedure.

After the switchover I believe some relay transmitters were switched off therefore the aerial maybe pointing in the wrong direction.

Yes, silly me, signals are stronger. Wondered whether they are overwhelming aerial booster. Prob not! Must have something to with my aerial and its orientation; will continue playing.
Yes, my home TV gets much better reception now from CP on its roof aerial.

OK, I've now tuned all 113 stations on Hannington (South) transmitter. It turned out that I had to change the direction of my aerial thro' 90 deg, altho' Hannington hasn't moved. Perhaps, as you suggest, a relay was taken out, altho' I thought I was pointing at the strongest signal.
I had to massage the tuning data of my TV tuner programs, cuz the muliplex channels and frequencies had changed over the switchover. Indeed a couple of the frequencies on the official Freeview site for Hannington were slightly out (by 0.2 MHz) sufficient for one of the TV tuner programs to skip over them until I amended them based on data from the other TV tuner program.
As regards the OP, I have no experience of WMC but perhaps its tuning data has run into the same problem.

I can now only get BBC channels

Which Area/Transmitter?
That's what I got before I corrected the frequencies.
