I am tweaking the playback to use LCCS 2.1 SDK and I haven't been able to bring up a recording yet. I have been trying to play back on particular recording with no luck today. Sometimes I get connected as follows:
Thu Oct 27 13:35:04 GMT-0500 2011 LCCS SDK Version : 2.1.0 Player Version : WIN 10,3,181,34
Could you post the complete access_log line for that GET request? I think that one on the items in the log line should be the time it took the server to service the request. Furthermore, I think that access_log will print out the line when it has completed servicing the request so, at this point, we are looking at 15 minute download for your 66Mb recording.
I am not sure why your client debug log stopped, but it could have been some timeout somewhere.
