If you don't want any of the channels on a particular transponder then don't map that frequency to a DVB-T frequency. As I found out the combined transponders for the satellites at 28.2 & 13E exceed the number of UHF DVB-T frequencies. It's also a good idea to omit transponders that aren't wanted as it keeps the numbers of channels down to a more manageable number. I think it was over 1500 channels that I found on one scan of 28.2 & 13E combined! MCE handles the few dozen channels for DVB-T OK but the same interface for hundreds or thousands is very unwieldy.
Another tip is to arrange order of the transponders in the text file as far as possible in the order that you want the channels numbered e.g. your BBC 1 region at 1, BBC 2 at 2, your ITV region at 3 Channel 4 at 4 etc Again this saves time reordering the channels.
DiseqC switches like this
http://www.dvbshop.net/product_info.php/info/p83_DiSEqC-Switch-4-1-waterproof.html allow you to switcth between multiple LNBs & they can be cascaded. If you aren't using DiseqC then the relevant entries in the file should be 0, 0, 0, I can't recall exactly how my DiseqC switch is set up but what works for me is 28.2 1, 0, 0, & 13E 1, 1, 0,
It is possible in the registry to create an exclusion list of channels that you don't want MCE to scan for you.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\GLID\ExclusionList
This is to take account of channels that for some reason MCE can't handle in DVB-T. Originally this was the DVB-T radio stations but now includes Bloomberg, BBC Parliament. There are a few ways of populating this list. You can just do it by hand. Alternatively you can take the "dumper" tool from the QuickGuide package to dump a simple clear text list of all the DVB-S services MCE has found in a scan. Then enter in the ExclusionList all those that you don't want. Then you scan again. This time the scanner will ignore all services found in the ExclusionList and not even add them to the database so you end up with a more manageable number of stations. However the "opportunistic scan" of MCE will always run in the background during live TV or recording and pick up any new stations which are not in the ExclusionList, so you will every so often get some unwanted stations.
I just found a nice tool on a German site that allows you to edit the exclusion list, filter & re-order channels all from a Windows interface & seems much better able to handle hundreds of channels rather than the MCE interface. Unfortunately my German is very limited so I am not quite sure of all the functionality yet. I have got it to generate the entry for ExclusionList in the registry before rescanning but then discovered that it had zapped all m EPG data which I had to download again. It all seemed to work OK & does allow for quicker sorting of channel order & setting channels blocked or unblocked. At the moment as far as I can see all it is missing is a function for mapping EPG listings to channels

I have attached my current .TPS file used as input for the DVB-T Mapping tool. This has only the transponders that I am interested in on 28.2E & 13E i.e. no Sky Sports or Movie channels. It should be a reasonable starting point for anyone.
BTW There are no listings for Hotbird in your attached file
