Pixellation & Stuttering - TVE

Anything I can do to improve?

Having an inordinate amount of pixellation & stuttering on many TVE channels (Live and Recorded)

For example on BBC HD:

Very strange. Is this happening on all channels?

Yes, at least those I’ve tested. 3-4.

Would a more powerful processor help?

Where are you running the dvr?

NAS : Qnap 251A

BTW: Just tested 30 channels on TVE. A couple are better (almost acceptable) and some worse than BBC HD.

Could be an issue on some channels. I don't have BBCA here so I haven't been testing with it too much.

NASA seemed to be the best. But most are really annoying.

Is it worth it to try to identify stream resolution from these broadcasts?

Also, was thinking of getting a Synology DS-918+

The skipped and transport_errors numbers here should be zero. Something seems buggy. Are you seeing these on other channels as well?

I’ll record a few channels to test

Also, when I stop recording in the middle of a job and/or have a job that can’t seem to finalize
I get this...NOTE: The last one (job on 7/25) is still in list. How can I delete these entries?

Bug fixed for next build.

Thank you...

Any further thoughts about buying the DS918+?

Can you tell me how long it takes for your Qnap251+ to process/comskip a 1hr HD recording

These are really high. Does this happen for you on AMC channel?

I think there's something seriously wrong with your DVR. Either failing stick of RAM, or the disk is failing. Or something's up on your network (I did see a timeout errors as well).

Finally setup my old Synology NAS (DS1513+) with ChannelsDVR (2019.07.27.1817) to use only Xfinifty-TVE for its source.
Just started two recordings using TVE on BBCA and AMC.
AMC Colombiana (2011)
BBCA Planet Earth: Yellowstone - Summer

They should be completed in 5 minutes.
Will update post with stats when they're done.

They look fine.

@DebbieFL
Noticed a couple "Sharing existing connection " log entries.
Are you viewing the same channel while it's recording?
Did you check the CPU usage on your NAS while doing that?

Sharing only 1x

No I wasn’t monitoring usage. I’ll do that on next one

Thanks
