I just bought a DVDR72 off of Ebay, thinking it was supposed to be Costco’s identical version of the 75. It appears that there are 2 versions of the 72, a 72 and a 72/75. When you hit the edit menu (FSS) you only get “New Index picture” and “Divide title”. There appears to be no way to add chapter marks during playback to hide commercials. This is also the way the FSS menu is displayed in the manual, although they say you can hide chapters. Does anyone know how this would work, they don’t mention it again in the manual. Thanks.
