As advertised for two years, several stations re-homed their digital transmission to new UHF and VHF frequencies.  Re-scanning WMC has not recognized these changes.  Is a new mapping file going to be downloaded, or do I need to manually add and delete stations in the configuration files?  Should I wait until tomorrow to re-scan? 

None of the guidance in TGB or in the WMC interface provides any detail about how to manage these changes.  I only see vague general information with no guidance about how the transition was really supposed to work with WMC.

Same issue here.  Lost DTV 8, 10, and 49 signals in Portland today - can't find how to point those channels to the correct, new frequency.

Help!?

Here's a link to the FCC document listing the new channel.  A couple you mention have changed.

http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf

I used the information from the first link to several missing channels back where the frequency had changed.

I just added the new frequencies in Portland to my WMC 7.

Settings>TV>Guide>Add Missing Channels>Add DTV Channel

Then add the Channel # and RF #
8.1 ----> 8
10.1 ----> 10
49.1 ----> 30

Once you add those channels, you can edit their Listings Settings to use the listing from the old channel in the Guide, then remove the old channel with the wrong rf from the guide.

Kinda a pain, but it worked for me.

Thanks all.  Got it all set using: http://thegreenbutton.com/blogs/pnear/archive/2006/09/12/202708.aspx

And here for the physical channel numbers:

http://www.fcc.gov/fcc-bin/audio/tvq.html

And if I am reading the FCC info correctly, 12 KPTV in Portland is due to change also from 30 to 12, but as of 11:15PM they are still broadcasting on 30.  Will check again tomorrow.

Sheesh, what a pain...MCE tweaking is getting old...sure hope W7 is much more robust out of the box...big sigh

This worked for me (I'm in Vancouver, WA) - close Media Center, put the xml data below in the file atscprefs.xml in the folder ProgramData > Microsoft > eHome > EPG > prefs. This contains overrides of channel settings that are not yet being provided correctly. You can compare this against the atscchannels.xml file, which is the default channel settings. Next, start MC and run the TV tuner setup again, and you should be good to go.

I'm finally getting channel 49 again after several months of no signal. You'll need to replace the { and } symbols below with the correct less-than and greater-than symbols (the web page was giving me grief including it the correct way).

{?xml version="1.0"?}
{channels}
{channel callsign="KGW" userAssignedName="KGW" version="0" physical="8" major="8" /}
{channel callsign="KOPB" userAssignedName="KOPB" version="0" physical="10" major="10" /}

Hi all,

I have tried all the above and still can’t get channel 8 KGW to work it works fine on my other two TV’s in the house using the same antenna. I have tried both the physical channel of 40 I think which is what the guide uses when automatically downloading guide info. I got channels 10 and 49 to work by the above instructions but have not gotten 8 to work even when changing the physical channel to 8.

Any ideas would be appreciated.

No. All you need to do is LIE to Media Center. Go into Set UP Guide an specify a new ZIP code in another part of the country. When that has completed, reboot and run Guide Setup again using your actual ZIP code. -- I should come up correctly; the problem is that the guide does not update the channel/frequency map if the one specified is the same as previous... (This is a common software bug because the problem is usually overlooked by the developers.)

I have figured out that if I start to record something on another channel and then tune to channel 8 it works fine. So one of my tuners must be incapable of tuning in the physical channel of 8. Is this correct? I’m not sure of the exact model # of my two cards. Is there a way to find out which one card media center use first?

Did you add 8.2 via Add DTV Channel?  It's probably that you pointed 8.2 to the correct physical channel and when you tune through it MCE is able to keep the correct physical channel when you hit 8.1 - but it won't tune 8.1 on its own without going through 8.2.  I had similar issue until I went with an approach based on PDWhite's suggestion.

1) Rename the MCE xml channel configuration files to Old_...xml (fill in the ... with the three xml configuration file names)

2) Rerun the TV Tuner setup (steps 1 and 2: not sure if these are required, but I did them anyway in case they would reset something)

3) Rerun Guide setup and specify a zip code totally out of your area, selected a provider, downloaded the listings for that zip

4) Repeat 1, 2, and 3 but using Portland zip once you get to the Guide setup steps. 

Worked like a charm for me.  Still have to go add the sub-channels that MCE doesn't pickup automatically, but all the main channels were present and correct for me. 

Thanks for the suggestion PDWhite, much more straight forward and less error prone than editing the xml files.

I havethe same problem. Can't get 8.1 now since the change. Used to work great in HD, but somehow it's gone. Anyone have any answers

Did you follow the procedure immediately above?
