Random pause when watching recorded tv

I am getting random pauses when watching recorded tv - specifically Dateline. The pause in video ranges from about 10-30 seconds. Log is below.

This is bad and means video data is being dropped. Usually this is due to resource exhaustion, commonly in disk write throughput. I would check the Task Manager while recording to see if CPU, RAM or Disk are maxing out.

Joshua_Moore · March 21, 2020, 3:09pm

I wonder if it was just too much to be watching, recording (2 shows), and processing commercials on another show? I normally don’t have problems, it just seems like it happens when my wife is watching/recording her shows, lol. We’ll blame it on her!

I’m betting my Drobo 5C (DAS) is probably the weak link, it has decent transfer speeds (USB 3.0) when watching 40GB Blu-ray rips, I usually see about 350Mbps but I’m guessing multiple devices reading and writing to it isn’t the best. It has WD Red (5400) drives in it. It’s hooked up to my Alienware Alpha PC which shouldn’t have any issues with anything thrown at it.

Here’s what it looks like while recording 2 stations and watching one.

Any suggestions?

Were you getting buffer full errors in the logs at the same time you took those screenshots? The screenshots show the disk is basically idling.

Joshua_Moore · March 22, 2020, 4:03am

No, I just purposely set the DVR to record 2 stations while watching a 3rd. I was hoping to recreate the issue.

I’m kinda confused because the screenshots were live while running 3 shows so I’m not sure what my issue is. Disk S: is the Drobo that all media is stored on and recorded to. Disk C: is the OS and the PC that is running Channels in the system tray.

I’ve turned off commercial skip thinking that maybe it was causing an issue. I also changed the transcoding from hardware to software - although I know that will only impact the PC when connecting remotely.

I’m also confused why my video card has no activity. Is it not used at all with the HDHomerun and Channels?

racameron · March 22, 2020, 4:20am

No, it isn't. Just the disk and network. It doesn't need the graphics subsystem except in the case of hardware-based transcoding.
