[QUOTE="georgius, post: 1071568, member: 107951"] I analyzed only TEST3 case and found something. First, filter wasn't designed to allow calling Load() method multiple times. In that case, filter drops received data. IPTV filter was always destroyed and created before calling Load() method. I know that stopping graph and calling Load() is much more faster, but in current case it doesn't work. Good news, this can be fixed :) Second thing is missing data in RTSP stream. In TEST3 case was tv service started and on tuner 0 was selected BBC WORLD (PMT 0x13BA). Then was channel changed to NATIONAL GEO SD (PMT 0x053C) and then was channel changed to SCIENCE CHANNEL (PMT 0x0564). Then was channel changed to INVESTIGATION DISCOVERY, but in dumped output is nothing about that channel. In tv service log I found that for SCIENCE CHANNEL was some sequence: [CODE][2014-03-21 16:25:10,883] [Log ] [34 ] [INFO ] - DRI CC: tune channel 122 "Science Channel", sub channel ID 0 [2014-03-21 16:25:10,884] [Log ] [34 ] [DEBUG] - existing subchannel 0 [2014-03-21 16:25:10,886] [Log ] [34 ] [INFO ] - subch:0 OnBeforeTune [2014-03-21 16:25:10,888] [Log ] [34 ] [DEBUG] - DRI CC: tuning...
