Video stops playing...just freezes during the last few minutes of show ending; audio continues fine.

Hi makaiguy and thank you so much for your help.  Everything was going smooth and I was following your instructions to the letter.  Got to the end and was ready to reinstall the channel....and it was gone!  Looked everywhere,  but the Favorite Sitcoms channel was MIA.  Dagnabit!  Wish I had more knowledge where all these channels come from anyway, how the content is gathered, how they make any money without paid commercials, etc.   Anyway, thanks again.
