I too have had that problem. The way I found to continue watching the program was to go near the top of the screen and 3 icons come up. An X to get out of the program, a box to make it full/less screen and the last is 2 boxes overlapped to make it a micro screen. If you click on that it will take you back to either your DVR or the TV listings at the show listing. It will say 'resume' as one of the options. Click on that and usually it will pick up where you left off. Sometimes I have to do that multiple times because I accessed it from another network not Comcast's. But, that is what has been working for me.
