Hi,
I am running Margro's build with TSReader on a win7 machine, and everything was working great up to a couple of week ago, where all of a sudden playback of all channels started stuttering. Every couple of seconds the playback halts for a short while and then playback catches up.
I am not sure what changes in my system as this didn't use to happen before.
The weird thing is that if I start recording a programme, playback is absolutely fine.
Record = fine.
View normally = stutter.
Any help would be appreciated.
Thanks!

Bump, is this not happening to anyone?

Yep, same problem here with 4TR on openelec.
After some research I found out that it only happens when the viewing(reading)point is close to the writing point.
So when I pause the live stream for 8,5 seconds(for me), the video stays stutter free.
I have set "dalay after tuning" in the 4TR addon config to 8500ms to work around this issue.

Thanks Glenn, I also noticed that if I paused for about 5-10 seconds or basically until the video buffer shows 100%, the video plays without a stutter.
I tried playing with all the available settings, delay channel switching and others and the stutter doesn't go away.
I also don't really understand why there should be a problem - shouldn't the video play catch quickly enough with the stream? Waiting 5-10 seconds for a clean stream sounds like a bug to me.

I've switched from MP to FTR and the stutter happens in both, probably due to both using TSReader.
I've also just installed VLC and channel tunning and switching there is instantaneous, and there is no frame drop or stutter in the video.
I can't understand why when recording is on there are no frame drops, but when it's off, it's as though the steam is not fast enough and frames are dropped.
Margro - as you wrote this and are most knowledgeable - can you suggest a way to fix these issues?
Thanks.

I can only guess. Without debug log files no help.
From the current information, it seems that my addon is reading too close to the end of the timeshift buffer file. Pausing for a few seconds will help in that case.
Is your backend running on the same machine or is there a network connection involved?
Could you try enabling the "Use RTSP streaming" option (TSReader using RTSP) and see if this gives a similar result?
