Description

After days (weeks) of trying to figure out why I get temporary stream freezes every few seconds/minutes, I finally realized that I only get them when the ecm reply arrives faster than (around) 220ms after the request.
I suppose this has something to do with locking, but I cannot figure out where the problem lies (maybe the reply comes before all requests are sent and they both try to access the same object at the same time).
As soon as the replies return to the normal speeds of around 300ms, the stream resumes normally.
Please note that this happens using an irdeto card (multiple ecm channel ids), don't know if it happens with different card types.
Any help would be appreciated, it is killing me!

Just noticed that this does not only apply to Irdeto cards, just happened with an NDS card, too. As soon as a key was received only 130ms after the request, there was a lock until the next key arrived at 3xx ms.

Please close this issue, I just noticed that all those early-sent keys are invalid (don't know why), and thus the image freeze.
