[mythtv-users] BE 2 - Remote Frontends Sluggish on FF

Hi Roger!

BE1 and BE2 are two separate computers,  both using whatever Mythbuntu 
was current at the time based on Ubuntu 16.04.  As for the logs, will 
upload to PasteBin shortly -- looks like BE1 (the one with no FF/REW 
issues) has a faster response to "VideoBuffers::DiscardFrames".  Also 
seeing where the wait time for video buffers is around 100 or so 
milliseconds on BE1 (the 'good' Backend) vs. 1000-plus ms on BE2 (the 
'sluggish' one.  Guessing that's the pausing I'm seeing but no idea on 
the next step.

As for the Wiki page re: Frontend Video configuration, yes -- if the 
wrong one will either get an error pop up when trying to watch a show.  
Thinking because the pausing occurs with all Frontends connecting to BE2 
there's a similar configuration on it (the Backend) I have wrong; just 
not going to randomly try things and really screw it up!

...Uploading to https://pastebin.com/u/Barry_IA in a bit....
*BE2*    is    mythfrontend -v playback    with the Frontend connected 
to BE2 (the sluggish FF/REW one)
*BE1*    is    mythfrontend -v playback    with the Frontend connected 
to BE1 (the 'good' one) but I forgot to update the audio and video 
configurations (on the Frontend)
*BE1a*  is    mythfrontend -v playback    with the Frontend connected to 
BE1 after configuring the audio and video.

(So also realizing my comment the other day about a script or something 
to more easily swap between the two Backends is more complicated that 
just copying in the two config.xml files.)

...OK, looks like they're posted.

Thanks!  Looks a lot simpler than something I did <mumble> years ago 
with a batch file!  (Probably a heck of a lot more efficient -- if 
Steve's channel skip routine makes his electric meter spin my antique 
batch file would make his meter pop out and fly! <g>)


> BTW, https://www.linuxatemyram.com/ is a useful read.
It is!  And does explain why the two stats weren't jiving.


Thanks!
Barry
