    I have a sony vaio desktop with 3.0 Pent-D and vbox external hdtv tuner.
    X300 graphics card, not sure of tuner card. 1gb ram.

    I have a roof mounted HDTV antenna and I get all channels on my HDTV. I
    connected the antenna to my vbox and ran through the MCE Digital signal
    setup. All channels show 6bars/100% signal strength, however, when watching,
    all channels hiccup/freeze except my CBS station which is perfect.

    I tried a new video card (Radeon X800xl) and there was no difference.

    Any ideas?

    What DVD Decoder are you using?
    Will a recorded program also stutter? If not then you may have a shared IRQ
    It is interesting that CBS is ok since it isa 1080i channel and ABC whcih is
    a 720p channel is not.
    What resolution are you outputing over what interface to your display(s)?

  3. Ray I had the same problem with the USB hdtv vbox, I fix the problem with a
    powered USB hub $9.00 us.

    Hmmm, I am not sure what DVD decoder I am using, how can I tell??

    I am just viewing this on my monitor, 1024x724.

    A recorded program will also stutter.


    Richard, did you have some channels that worked and some that didn't?

    I have read elsewhere a powered USB hub will likely fix this issue.
