I think something has broke in one of the recent windows 10 updates. I noticed that some programs no longer play. I noticed it for tonite's Once Upon a Time but it also failing on earlier episodes from this season and last that played before. I usually test playing it on my pc before I delete it on the TiVo. I also see the same failure on Marvel Agents of Shield, Agent Carter. Other programs I have saved still play ok. The failed programs play ok on video redo. The error I get is "Windows Media a Player has stopped working..." So I'm guessing there's something with Comcast on the codec they use for some channels. A CNN doc on the band Chicago is fine as well as a Tom Petty concert from MTV.
