Dear Sam,
Thank you for your reply.
I do use external player with buffering as you advised me about a month ago here. I only use a few of the movies sections which perform best. I actually check movies and very rarely watch a full movie. So in a week I might test about ten or fifteen movies, each for a few minutes. I am not looking for help anyway, just reporting back.
My image's GStreamer is not the new problamtic 1.6.1 or even newer 6.2. It is the reliable v1.6.0.
For the last two weeks or so, the hanging has gotten noticably much more. I have a feeling the sources are being less reliable but I guess the main problem is from the updated codecs. The only way out of hanging streams, not freezes, is if exit button would call a powerful interrupt procedure. But realistically I do not think you can do that effectively. Many people have tried to do that for E2 in various plugins (and even Kodi). but once it hangs on a difficult stream, it usually just hangs, sometimes even powerful telnet commands do not interrupt. Half the time after a few minutes it might return.
So I do not think you can fix that, which is why I did not ask for anything. Realistically as this grows in sections and becomes bigger problems will increase specially due to various codec updates. C'est la vie.
Good luck and merry Christmas.
