Can't see anything wrong on the server side. TsReader log is a completely different story. Frames dropped left right and centre.
Are you sure you have hardware accelerated video decoding enabled?
Using the AMD Video Decoder is unusual...

I have that particular client setup as per these instructions https://forum.team-mediaportal.com/threads/guide-perfect-playback-display-calibration.119610/

But you were right the TV tabs top two options were set to AMD Video Decoder. I've now changed to LAV.

I managed to fix the issue before this by stopping all 3 clients and restarting MP. Stuttering stopped on the 2 effected clients.

Thanks for your help

Just to report back, no further stuttering issues after changing those codecs to LAV. Actually I've ticked the box on the Videos tab to control .ts files from Videos tab.

I have however now got a new problem. DVB-S volume control is fine. However on DVB-T channels pressing volume up or down on my PC media remote has no effect. I have to use the Amps remote.

Logs attached, last action taken was up down volume on DVB-T which didnt work, then up down on DVB-S, which was fine.

Any advice greatly appreciated

It has nothing to do with DVB-S and DVB-T and everything to do with audio stream type and LAV configuration.

Channel 1 (4seven):

[2014-04-19 18:28:14,833] [13125358] [ e00] - video pid: 30 type: MPEG2
[2014-04-19 18:28:14,833] [13125358] [ e00] - audio pid: 40 language: eng type: MPEG2 - audio
[2014-04-19 18:28:14,833] [13125358] [ e00] - audio pid: 41 language: eng type: MPEG2 - audio
[2014-04-19 18:28:14,833] [13125358] [ e00] - Subtitle pid: 50 language: eng type: DVB subtitle 2

Channel 2 (BBC 1 HD):

[2014-04-19 18:32:13,660] [13125358] [ e00] - video pid: 30 type: H264
[2014-04-19 18:32:13,660] [13125358] [ e00] - audio pid: 40 language: NAR type: MPEG1 - audio
[2014-04-19 18:32:13,660] [13125358] [ e00] - audio pid: 41 language: eng type: AC3
[2014-04-19 18:32:13,660] [13125358] [ e00] - Subtitle pid: 50 language: eng type: DVB subtitle 2

Based on your audio preferences (prefer AC3 enabled, no languages selected), the audio track selected by MP for the first channel will be PID 40. MPEG 2 audio will always be decoded by LAV and streamed to the audio device as LPCM. You will be able to adjust the volume because LAV decodes the audio.

The audio track selected for the second channel will be PID 41 - the AC3/DD track. I can only guess you've configured LAV to bitstream AC3. Therefore LAV does not decode the audio, ergo you can't adjust the volume with the HTPC - has to be done on the audio device (because the audio device decodes the audio).

Please check your LAV settings for bitstreaming:

Really appreciate your help here - my LAV is configured exactly the same as the example you display apart from Auto A/V Sync correction is not ticked on mine and Expand Mono to Stereo is ticked on mine.

What do you suggest I do next?

edit - I also only tick that prefer AC3 enabled in Audio preferences as it removes audio description.

 

[mm1352000]

Hmmm, odd.

Please could you tell us about your audio setup - sources, connections and endpoints - and how you adjust the volume (ie. whether on PC, receiver, TV etc.).

 

[mm1352000]

Oh, actually...
I see you're using the MediaPortal Audio Renderer for audio. Please try the default DirectSound device (or other). MPAR is not the best for live TV and as I recall may try to bitstream the AC3/DD, preventing volume adjustment. I could be wrong but worth a shot.

This PC machine is client 3 in my system specs and provides the media to the main TV in the house via HDMI into a Sony STR-DH520 Amp and surround speakers which then outputs to a LG Plasma TV (TV speakers are not used). The volume is normally controlled via a WMC clone remote on the PC. Additionally its possible to adjust the sound via the Sony amp, but I try to avoid this and use the PC remote.

So on the Audio Renderer I have the following options and their results when using them

AMD HDMI Output - This enables volume control on everything (Live TV - both types - and various film formats)
Default DirectSound Device - This enables volume control on everything (Live TV - both types - and various film formats)
Default WaveOut Device - This enables volume control on everything (Live TV - both types - and various film formats)
DirectSound: AMD HDMI Output - This sometimes does not enable Live TV playback (video and sound) and on films formats has no sound at all
MediaPortal Audio Renderer - Issues as described previously

So I've left the setting on Default DirectSound Device - lets see how it goes, do you think this is best?

Many thanks for all you advice

Yes.
