Several weeks ago, someone here posted a fix for the folder issue and it worked for me on my 722.Yep still PATIENTLY WAITING for DISH to bless my 722ks with their non-folder-bugged goodness. Hell I've had to deal with that stupid bug for what 6 months now? I don't guess another few weeks/months will kill me.
Try turning folders off, then back on again. I did this and the 'Folder bug' went away for me...
