 Hi
 I have two computers running MythTV. Both are independent of each other.
 Both run Fedora 25 with a Hauppauge WinTV-quadHD TV Tuner (FreeView). They
 have RAID1 SSD for the OS and DB, and RAID1 HDD for storage.

 I built them during the end of last year and everything was working ok. I
 usually use MythTV to record programs (SD and HD) and then watch them
 later on. Up until recently, all recording have been good with no glitches
 in recording quality. I mainly use one computer for primary use and the
 other for testing.

 A couple of months ago (not sure of exact date), I noticed recorded
 programs (mainly HD) contained pixelation (a couple of seconds every
 approx 30minutes or so). I think this was caused by a Fedora update, but
 not sure what package(s) caused this error. I believe this to be the case
 as I had not applied Fedora updates to my test computer and recordings
 worked fine on the test computer, until again I applied all the Fedora
 updates.

 I am unable to undo the Fedora updates, but have tried a previous Linux
 kernel to no avail.

 Is there a way of debugging MythTV / Linux to find out what is causing
 pixelation?

 Would you have any ideas of what is causing this?

 Many thanks, Abbie,
