ralphmans - I agree that it is probably not your DVR. I think the broken u-bar reinforces that. nut I am sure if the DVR is involved with U-bar.

I believe at&t has to fix your Yahoo interface. The reason I gently pushed to reboot the DVR was just to get by it.

Just in case the u-bar relies on the RG - Pull the plug on the RG & DVR & STBs, Replug RG & stabilize, same for DVR, then STBs.

Or, Can you disconnect or unplug the DVR and try the u-bar from an STB. If broken -

call at&t again with the broken u-bar complaint & see if they wil work with Yahoo to fix it. Say DVR is not being used - ubar should work without DVR. No need to reboot DVR.
