Just bought a 176T a few weekends ago, took it out this past weekend for the first time. Went to show a movie to the girls and could not get video to work. Had sound from a DVD, but just no video. TV was set to AV mode, yellow composite cable was hooked to AV-In-Video on back of Jensen tv as well as to the TV video out port in the TV cubby. Noticed the stereo/dvd player was installed with square drive screws and I did not have one of those bits at the campground. But I do at home and took it all apart yesterday. Found the AV cable end was broken off inside the jack inside the wall. Pried out the pin from the broken plug end and replaced the cable and we are now cooking with gas.
Just thought I'd share to check the AV ends inside the wall if you just plain can't get video on the TV from a DVD.
Rest of the R-Pod seems to have worked quite well.
