Video player is experiencing issue where for some videos it will play only about 50-55 seconds of video, then freeze. It never unfreezes that I've seen. You can go back to queue, select same video again, and it will play another 50-55 seconds worth, then freeze again. This can be repeated forever to painfully see something in 50 sec chunks.
I speculate there is a problem with the buffering mechanisms and the original 55 sec burst probably corresponds to amount downloaded when connection is first made, but additional blocks are never forthcoming when requested.
More data points:
1) The problem effects some series but not others. For example, the "Fairy Tale" series is not watchable on the PS4, Something which has remained constant for months. This issue seems to affect specific episodes or groups of episodes of a series rather than an entire series (e.g. episodes 1-20 of a series will play just fine, but not 21-40).
2) This problem appears to be specific to the PS4 version of the application. I have not observed this so far with Roku or Android versions, nor with browser playback, but I use these latter 3 infrequently so that may not prove much.
3) Premium membership.
Note: I have tested the other platforms mentioned above and for me they always worked even as the PS4 version continued to fail (I even tried them in parallel). But I *really* want the PS4 version to work, since that is the only way I can watch the vids on my main TV!
Observation: this problem seems to be a permanent condition for whichever episodes are impacted; that is, this doesn't just randomly effect any episode. This is probably a valuable hint. Perhaps for example these breakage points in ranges of videos (e.g episodes 1-20 working and 21+ not) correspond to specific sub-servers which host particular videos. (?)
