I've heard were the person who owns the video content has monetized the ads that get displayed.... and thus the videos will not play at all on mobile or other devices if an ad is blocked or unable to display..... Not sure if this is what's going on here though.
Yes - I understand those monetized vids can only be watched on youtube and will not play on other devices, but that's NOT what's going on here. The videos I tried to play will play on other devices such as my smart phone & blueray player, but not the Hr24 DVR *if* the video is over a certain length. But why?
I found someone on another site with the same issue and someone responded that if the youtube video is over one hour and 30 minutes long, you will get the unable to access media error on the D* DVR. I think that might be true because I found a video that was one hour twenty minutes and it played fine. Funny how the other devices didn't have a problem playing it not matter how long it was.
Go to youtube and in the search type coast to coast, long - those search terms will pull up all coast to coast videos that are long, try to play one on your smart phone or other device and they will play, but not on the DVR.
