Losing time when watching videos fullscreen on my old CRT TV.

FYI. In http://www.rage3d.com/board/showthread.php?p=1336503410 forum
thread, http://www.thesycon.de/dpclat/dpclat.exe (DPC Latency Checker)
was mentioned so I tried it.

I started this program with a clone of my desktop to CRT TV (640x480).
Green and low results. Then, I started up a fullscreen MPEG-2 HD video.
Then, things shot up with yellow and red.

I stopped after a few seconds with enough datas. I exited dpclat.exe and
put my display back to single display to my 19" LCD monitor (1280x1024)
only. I repeated the tests, but they appeared to be similiar:

do you think? They look identical to me. The time slow down only happens
in clone display mode with fullscreen videos.

Hello.

How come my PC/Windows' clock loses a few seconds per minute (seems to
pause about every four or five seconds for about a half of a second)
when I use CRT TV clone and watching videos fullscreen on my old 20" CRT
TV (from 1996)? If I am not watching videos on it or use single display
mode to my DVI/VGA 19" LCD monitor (1280x1024) with videos, then I have
no problems.

I used ATI Catalyst suite display drivers (v9.7 and v10.12) to clone to
my old 20" CRT TV to show videos fullscreen. I am using an old updated
Windows XP Pro. SP3, 2+ years old ATI Radeon 4870 video card (512 MB of
RAM), Intel quad-core systems, etc.

What's up with that and how do I fix it? Thank you in advance.

FYI: Someone, in that rage3d forum thread, suggested HPET setting in
CMOS/BIOS. I found it and disabled it since it was enabled. I also
changed my KVM to a two ports to see if that helps. Both did not fix it.

I am changing the CMOS setting back later when I reboot again.
