A couple of nights ago, I noticed my TV/DVD combination was acting up. PAL DVDs would play with a horrible irregular juddering motion. I checked broadcast TV and the PS3, and they were both fine; I checked the DVI/HDMI cable, that was fine also. I started to suspect the DVD player. Friday, I bought a new DVD player. $44 at Fry’s Electronics. It had the same problem. Further investigation and experimentation eventually revealed that the issue was a setting on the TV.
