[QUOTE="jonathantwynham, post: 1165199, member: 138813"] MM, Appreciate your help, but as the original title of the thread, I am still actively troubleshooting the pixelation and stuttering of live tv as I have never managed to solve the issue.. [INDENT]1. Ensure your forum profile system specifications are fully up to date. [INDENT] I have updated my system specs to show correctly.[/INDENT][/INDENT] [INDENT]2. Reduce/simplify the steps or conditions required to reproduce the problem as much as possible. For example, if you can reproduce the problem on the server by itself then do that (ie. completely exclude the clients).[/INDENT] [INDENT][INDENT]The network test is using software called 'LanBench', it uses winsock to send and receive data packets. It can be configured to receive packets from another machine or create a loop and send and receives packets on the same machine. I have it set to send data from itself to itself - in effect the packets are going from the TV-Server to the network switch and back to the TV-Server. I am also testing the effect of network data on [B]solely[/B] on the TV-Server...

Describe the situation (eg. the conditions when the problem does and does not occur, test(s) you're performing etc.) in full, including dates, times, channel names, and client/server involvement where appropriate. [INDENT]I have ruled out the HDD load as my server is now a completely different machine with completely different hard drive installed, and the extra addition of a solid state drive purely for timeshifting. This is also a barebones install on the server - only the specifics needed to run TV-Server and windows. No antivirus, no firewall, no MSE, literally nothing that can affect HDD load other than TV-Server. I dont need to include dates/times as it does this every time I run the network test. If we are watching TV and not doing anything our of the ordinary it only happens on HD channels, primarily ITV channels, SD channels behave normally. If I run the network test and/or copy data to/from any other our laptop / file server then it will happen on any HD channels and sometimes with SD channels.[/INDENT][/INDENT] [INDENT]4. Provide full debug-level log files from both client and server using the MediaPortal Watchdog tool where available. [INDENT]Log files from TV Server attached..[/INDENT][/INDENT] [/QUOTE]
