You are putting it to the test. I love it.
We are aware of this specific issue, but it looks like it’s on the PMS side, not specifically the client. The issue will arise when the capture buffer is pruned. This can happen for extended live TV playback, to reduce the size on disk. There is a an issue raise for this, but I can’t supply any ETA for that.
@ljunkie Thank you for the quick response. I have no issues testing stuff like crazy when it’s getting attention and progress is being made. Thank you and your team for that. Usually my Live TV doesn’t run that long consecutively so it shouldn’t be an issue for me now as the recent fixes really improved the Time Shifting on the Roku. Once sports start up again, it could become more of an issue. So if I understand you right, say I let Live TV run for a few hours, it will automatically delete out some of the previous “live tv” shows in the Transcode\Sessions directory and by design, you can’t skip to the actual beginning of when you started watching Live TV?
You are most welcome! Hoping we’ve improved the experience, which is the way it should have always been.
That is correct. You won’t have an endless buffer to seek back to. I should mention this won’t happen if you are recording.
I ran a test with my Roku where I set a recording, started from beginning when it was near the end of the recording, and then continued to watch Live TV after the recording was done. I was pleased to find that the recording transferred to my library correctly (with commercials skipped) and I was still able to continue watching Live TV beyond the end of the recording. This included rewinding back to the beginning of the recording from in the Live TV session, and correct time shifting.
I didn’t do the extended Live TV test, but thank you to @pbenzschawel for finding the issue and @ljunkie for giving us details on how to work with it until the problem is resolved.
I had my first “real” test using live tv last night. I had set a program to record and started watching it about 20 minutes after it started. I started from the beginning and all was good. When it came to skipping through the ads (a 4 minute ad break) I noticed that there was some odd behaviour with the skipping, it didn’t work. Normally with a program I have already recorded I can press it 8 times (8 x 30 seconds) and it works perfectly, but with watching a live program it did weird stuff and was unreliable. I would skip forward 30 seconds and I would see the progress bar jump forward and then jump back so that I would either end up where I started, or it would only move a few seconds forward.
I don’t have logs but I will try to get some.
This is a Sony TV running Android TV.
Yeah, some logs would be much appreciated 
Hey Dave - do you need client logs as well?
I was recording the TMZ Investigates: Tiger King on Fox. I started watching about 30 minutes after the show started using Roku Preview Client 6.5.2. Everything worked perfectly. I was able to skip through commercials without issues. It would be great to see video preview thumbnails during live TV but beggars can’t be choosers 
I’m hoping someday Plex can implement that, or at least have a setting to be able to toggle it on or off for Live TV.
Yeah, client and server logs, please
Cheers @DaveBinM - I PM’d you with the logs.
I’ve been happily using 6.5.1 both in preview and now the production app. I didn’t even check in for more updates. 6.5.2 preview seems to work just as well for me.
It seems that the specific bug to check for is the “trimmed” buffer scenario, correct? I’m unaware of a setting for the buffer size - is there a duration I should be waiting before trimming should occur? I’m under the assumption that everything thing will continue to work well for me too but if I can add one more data/test point for you, I will.
DirecTV was the same way with their DVRs, you could only go back like 45 minutes (not sure the exact length of time) in the live stream buffer.
Frustrated. Trying to watch live TV (a program that is currently recording) and the experience is going backwards. Can’t skip properly, audio switches back from what I’d set and then it freezes up.
It just seems like this is never going to work.
I tried this a year ago and got frustrated and canceled my plex pass
I log in every couple months to see if there has been any progress. nope. the dvr has been broken since inception and this thread has been going on for 18 months
I switched to channels dvr and the experience has been great check it out
There’s been a regression on my nVidia Shield PMS server/client since the introduction of the new player with live TV. Previously it worked as long as you didn’t go into “the next program” timeline. Now skipping forward the first time will skip back to the beginning of the recording.
Yes, so many people buy Plex, including me, just to find out that the DVR doesn’t work properly. Almost two (2) years into this thread now. Switching to Fancy Bits ‘Channels DVR’ provides an experience that is nearly perfect in terms of DVR functionality. Certainly worth the extra few dollars.
I have seen absolutely no improvements nor fixes to time shifting on the ROKU platform. That one more bug must be “time shifting plain doesn’t work”. I’ve seen the “skip back to previous show” reported elsewhere in this thread, the skip to random spot, the frozen progress bar, the skip to end on FFW, and every other issue I’ve read in this thread. They ALL still exist.
I’m running the most current windows server on an 8th gen i7 and 16Gb memory, Hauppauge quad PCI, a 2019 ROKU Ultra and a wired Gb network with one switch in the path. Also tuning is horrendously slow and fails often.
I gotta give the fan boys and the plexies credit for have a lot of fortitude in the claims of LiveTV experience.
From what I can tell from the rest of this thread, it’s not changed in almost 2 years.
DirecTV had a 2 hour live buffer for each of 2 active tuners and after the first year (early 2’s) it was pretty rock solid. I had DirecTV for 22 years. I was also a “beta tester”.
You might want to check the preview version of the Plex Roku client. As far as I can tell, it’s working perfectly.
I face a similar issue with tvOS app. I don’t have to wait for an hour to face the issue. I would say few minutes and it happens.
When I resume LiveTV, I can’t rewind or fast forward. In my case, It doesn’t skip to random spots like @pbenzschawel but definitively goes back to where it was pause. Sometimes, it also hangs there with spinning wheel.
You were speaking about the capture buffer. I’ve noticed when I was watching LiveTV the hard drive of the server got totally filled up.
My Plex server is in a VM machine with Ubuntu 18.04.
When I installed it. I left default options and it installed itself in /var/lib/plexmediaserver . Because my first drive is small (/dev/vda1 - 16 GB) I got lots of crashs.
So I symlinked /var/lib/plexmediaserver to my second drive (/dev/vda2 - 2TB).
Is there another folder I should move to /dev/vda2?
I have monitored a little bit when I paused and neither the RAM or used space on /dev/vda1 changed
