I've been fiddling with the service menu of an old sony tv trying to adjust its massive overscan problem, and couldn't get the sides of the image to actually be anything near straight. So I reset the service menu (by pressing 5, which caused "initial" to be displayed, then 0 to enter), and was able to adjust the settings from here and now it's just fine. But somehow the option for tilt correction from the regular menu is gone, and for the life of me I can't figure out how to get it back. I cannot find which service menu setting corresponded to it. Any advice?

Edit: Ok, never mind about any of this stuff. All fixed. But man they make it unnecessararily complicated.

Also now I apparently only have one video channel (I had two). Heh, ain't nothing like this happened before. Picture looks better than it ever has but... oh dear :S

I fixed the tilt correction thing, and found a setting that adds a video channel (OP0 in the service menu), BUT the second channel it adds is added as an S-video channel (which the TV doesn't have). Now I think I need to find a setting that disables a possible s-video input, which I would hope would make the second video channel a plain old video 2. I hope. Haven't gotten any answers so far, but I hope this one request is a bit simpler.
