    For some reason I lost my ABC channel last night, and of course the superbowl
    is on this station. When I run the setup for digital signal strength, it
    comes in at 6bars/100%. When I tune to this station I get a blue screen that
    says "No TV Signal" and then say to check antenna or that station may be off
    the air. I have tried running through the signal strengh setup and a reboot.
    I know this station is still on the air as I get the signal on my HDTV in my
    gameroom and the TV and computer are both hooked to the same roof mounted

    I also have Snapstream Beyond TV installed and the station comes in at 100%
    on their strength meter and it displays fine, so I could record it from
    there, but I like MCE interface better.

    Anyone have any suggestions??

  2. I've got the exact same scenario here (full signal strength; blue screen
    unavailable message) <f>. Naturally it's ABC eh? What ATSC tuner are you
    running? I've got an Aver Media 180 which up 'till now has been working
    perfectly (only had the system for a couple of weeks). I get the other ota
    stations just fine and was getting ABC just fine 'till a few days ago.

    Something I've noticed is that now if I try to switch ota channels it will
    start to loose picture (go black) and then audio after 4 or 5 channel
    changes. It then hangs with an ehshell.dll hang. End task, realunch media
    center and all is well again (I can tune to and watch a single ota channel or
    browse 'n watch any ntsc signal). Do you get the same behaviour?

    I'm really scratching my head over this one and have been through the gamut
    of driver updates, rollbacks, etc. I may take a quick look at the snapstream.

    I have not had that problem. I am using a vbox external hd receiver box. I
    have only had this setup for a little over a week.

    I had problems with media center live tv after an update that I downloaded
    last weekend. I removed it and had no problems.

  5. Are you able to run your atsc tuner with SnapStream and your ntsc tuner with
    Media Center simultaneously? If I can't get Media Center to pull in the
    errant ABC signal I want to have my OTA stuff in SnapStream and my cable
    stuff in Media Center (I also prefer the Media Center interface). But, I
    can't seem to get Media Center to release it's hold on just the atsc tuner so
    SnapStream can use it.

    I can't use them at the same time. I have to go into services and stop the
    media center receiver service. I really to not like the snapstream
    interface. Considering you have to pay for it I think it is junk. It also
    records in .tp files which I have trouble viewing in WMP.

    Did you ever get ABC to work?? I've been spending hours and hours
    troubleshooting this and I can't get it to work either. I just bought the
    ATI HDTV tuner, like you have 100% signal, live within 10 miles of the tower,
    and just CAN'T get it to tune in on Win MCE 2005.

    Yes, it did start working, of course it was AFTER the superbowl. I
    occasionally lose channels for no reason though. Last night CBS was not
    working, but it worked on my other TV's using the same antenna....

  9. I still can not receive ABC but have not had trouble with the other channels
    (NBC, CBS, etc.). I can recieve ABC just fine with BeyondTV (on the same

  10. I have been looking for a solution to this problem for over a month now. I
    have 3 digital broadcast stations I am interested in. NBC comes in loud and
    clear in MCE. CBS and FOX however exhibit the same behaviour. Full signal
    strenght, comes in on TV's tuner, comes in using other TV applications, but
    MCE simply displays the "No TV Signal" error. From what I have gathered it
    has something to do with the way the station is broadcasting and the way MCE
    intereprets it. I live in a rural area, dont' subscribe to cable / sat. so
    the analog broadcasts look terrible, so I am only interested in the digital

    The blame lies with MS on this one. If a TV tuner can grab it, and the tuner
    card can grab it with another application, the MS needs to figure out what
    they did wrong and fix it. I am not even sure how to let them know something
    is up. I fear we won't get any sort of fix until Vista rolls around.

    If you have 2 tuners you can use one for MCE and one for BeyondTV (which is
    what I do). Its a massive pain, because I have to use VideoReDo to convert
    from .tp to .mpg, but its a few minutes each day so I can watch shows when I
    want. I have been looking for another app that will do the digital broadcasts
    in .mpg so I can skip the MCE / BeyondTV issue all together.

    If you are trying to use both the normal Windows drivers for your tuner
    card and the MCE drivers at alternate times it appears that the different
    drivers are conflicting with each other. I suggesnt that if you want to
    only use MCE then you uninstall teh windows drivers for your tuenr card and
    reinstall only the MCE tuner card drivers from the uner card manufacturerss

  13. it would certainly seem that microsoft could / ought to be able to provide a
    clear and reasonably definitive trouble-shooting resource to get the various
    driver issues straightenned out. for whatever reasons, my system now does
    pull in abc (as well as the other previously received stations). i don't know
    what changed but there have been many updates and rollbacks in the
    intervening months. the only thing i can recommend is trying some rollbacks
    and install of different drivers to see if you can hit upon the magical
    combination that works. then be sure to save that configuartion as a system
    restore point to which you can return in the future when things again go
    awry. and wait for vista which will cure all <g> ...

  14. Good stuff. Certainly sounds the culprit here. Thanks!
