Heres a question, try recording the same movie a couple more times on hbo, and see if it is interrupted during the credits each time. also try a few other movies and see if its there as well. I have a feeling its only sometimes on some movie's but not sure.
Frankly, in todays day and age, the only way I expect to get a movie completely free of anything start to finish is if i buy the blu ray version.
I have a question too: If you hired me to do something top notch regurarly, wouldn't you expect it ALL the time? Wouldn't you be upset if I sometimes did a poor job for the money you are paying me? Same with premium channels...I expect it ALL the time.
But yes, those physical discs are the only way to go now.
