OK, so I tested the removal of the items requested (still with BIOS set
to fixed). After
> sudo apt remove mesa-va-drivers
I tried running the video in totem. Same problem as before - random
lags/stutters/freezes, usually < 1 second, but a few that were longer
(longest was about 2.5 seconds this time around).
So then I tried
> sudo apt remove i965-va-driver
then ran the video in totem. If anything, the problem became worse - the
lags were more prevalent, and the longest was > 3 seconds.
So I went back to mpv and ran the video there. There were minor stutters
(not long enough to call them lags - I would estimate they were mostly <
0.25 seconds) scattered through the video at random, but none long
enough to really cause me to say "this is unwatchable". However, I did
notice increased CPU usage - the system became noticably warmer to the
touch while the video was playing, and the fan kicked on high to cool it
(previous instances I didn't notice the fan kicking on - perhaps it did,
and I just didn't notice it. I have copied below the terminal output for
mpv, in case any of it is relevant (I didn't notice much different than
the past - just a warning about a decoder not supporting hardware). I
can re-run and see if I can catch a lag long enough for me to start
dmesg if you like. Just let me know what would help you most from this
point.

Also, should I reinstall the i965 and mesa drivers, or leave them
uninstalled for further testing? (I will definitely leave them
uninstalled until I hear otherwise, or for a day or so at any rate...)

Video freezes and stutters when using totem (audio continues fine)

Bug description:
Advised to file a bug report after posting on "Call for testing: Video
playback in 18.04".
Running 18.04 LTS as fresh install (not upgraded from previous version
- older version still installed in separate partition). Xorg session.
System: HP Pavillion DV7 (lm726av) - Intel Core i7 2630 processor,
integrated Intel video
Playing any local video file (regardless of video format - flv, mp4,
avi), the video will randomly lag in playback. Audio is not affected,
it plays back correctly. Very occasional lags in browsers (Firefox and
Chrome) on pages with a lot of active graphics (flash or HTML5).
Browser lags significantly improved after installing synaptic driver
for touchpad operation (I have no idea why this would affect video
playback - I simply note that it happened).
I can pick a random video on YouTube and watch it in Firefox or Chrome
without lag (even full-screen). However, if I grab a local copy of the
video (using, for instance, Clipgrab) and play it using Totem, I get
lag.
I was also advised to try using mpv - I still get lag in mpv, although
not as pronounced.
