The lid to this food processor was jammed shut, and neither of us could twist it open. I suggested using WD-40, but we didn’t want to put that on a container that would hold food. So, I tried cooking oil (safflower), applying it by using a toothpick to drip it into the seam between the lid and the vessel. After letting it sit for a few minutes, putting on some high traction rubber gloves, and more manual torqui, the lid came free!
I also had a problem with the video playback on my MythTV. The video was translucent and flickering with the MythTV menu visible through it, almost like a double exposed photograph. I fixed it the frontend setup menu: Setup->Video->Playback, changing Current Video Playback Profile to “High Quality.”
