I recently acquired a set of DVDs of "Incredible Hulk" and "Green Acres" from different people. All of these DVDs skip (I don't know what else to call it), meaning... every so many minutes the film slows for a second. What is this called? Does anyone know? It's tough for me, a DVD newbie, to explain this to fellow traders. The folks I got these from never mentioned this in our deal, so maybe this is just typical of homemade DVDs. Any help would be appreciated.
