I know this is a 2 month old post but I wanted to updated it.

After yesterday's finding of an issues related to my Shield TV and using
a USB Flash drive constantly inserted in one of the USB port, here's the
details.

This morning I was watching an in-progress recording about 30-40 minutes
behind real time. Absolutely no video quality issues at the 15 minute
point as previously observed. Also at the 20 minute point where the
network cuts to the local station for local news, I used the down arrow
to skip 10 minutes to the 30 minute point and it works as expected.

The version tested was mythfrontend-20200716-arm64-v31.0-79-g89d1991ef2.apk.

The hardware was a 2017 Shield TV.

Not sure if either the Shield TV or mythfrontend could have been using
the external USB Flash key for any caching but, whatever I did by
eliminating the USB Flash key seems to have fixed this problem.

This was not an intermittent problem. It happened everyday at about the
same timeline points.

So this seems to be my issue only which explains why no one could
duplicate the problem

Well, I can chime in and say that unrelated to MythTV, I had a friend who
thought it would be good to put a USB 2.1 drive into the Shield to allow
more storage for Kodi metadata. With no button presses or configuration,
it used the device for data and caching. Of course, it could not be
written to fast enough (cheap stick), and there wewre lags and glitches all
over the place. Of course, as usual, when asked - "nothing has changed"
was the response, but clearly something had.

Regardless - all I am doing is confirming that external USB on the older
Shields will throttle things.

I appreciate the data point. Even though my Shield TV has usb3 ports and
my usb memory key was usb3, I think that internal storage has to be faster.
I'm only using USB external storage for transfers from now on.

I've had no issues since removing that USB stick. I did lose one app, but
quickly reinstalled it.
