Argh. Made the mistake of hitting the yellow button while trying to un-skip a channel. That un-skipped EVERY channel.
Now I'm back in skip-channels ***, where there's no simple way to skip blocks of channels, where skipping a bunch of channels in a row leaves bunches of skipped channels un-skipped, and channels I've skipped keep on un-skipping themselves when I try to skip other channels.
Cox has been worse than useless in resolving this obvious problem in their broken software. No doubt they'll make some brain-dead solution like replacing a working piece of hardware to get a new version of software that, without any doubt, won't have any sort of a fix for this problem in it either.
