I am having problems with all 4 discs of That 70s Show Season One. They are all freezing up on the chapter switch, sometimes they just freeze for 3 or 4 seconds, sometimes the freeze for 30 or more. I exchanged my first set last night for a new set and I am still having the same problem. I have near 200 titles on DVD and this is the first time I've ever had a problem like this. I was hoping to come here and find a thread already (hoping it was a big manufacturing glitch) but haven't seen anything so I thought I'd be the first to ask, is anyone else having this problem? My DVD player is a Sanyo, if that helps at all, and it's about a year old. Any input would be appreciated.
