dvd studdering

setup:
dual LCD
2.26Ghz SC400
ati 9500
1gig ram

I'm watching a dvd and when I'm browsing on FF the playback studders. Considering my system specs... this shouldn't happen? right?

right now Windows Task Manager says this:

Memory usage:
firefox.exe 64M
powerdvd.exe 48M
svchost.exe 27M
trillian.exe 20m
iMon.exe 12M
explorer 10M
... (the rest is under 10M)

Physical Memory (k)
total: 1047552
avail: 508312
system cache: 666456


anything else I need to provide?

I just got the exact same problem, FF was sucking up 80% of my CPU time. rather wierd.

Close it and then reopen

I did that. I even searched on "FF memory leak" and I made the changes here:
http://kb.mozillazine.org/Config.trim_on_minimize

still have the problem. FF was running at 100M+ memory usage but it's much lower now. just tried it with IE and same thing, so I don't think it's application specific (ie FF is the main cause).

Chart the CPU on Performance tab and see if it spikes near full usage, particularly while browsing pages with lots of flash or other animation. I remember a long time ago there was a problem with Radeon drivers where animated GIF's would cause spikes. In any case, even though DVD should not be demanding on such a system, try toggling Hardware Acceleration. Indeed, check CPU useage with HWA on/off when not browsing and again while browsing. Also, is audio being decoded in software by PDVD? Another active decoder such as Creative's could cause a problem and should be disabled.

CPU does go up when I start browsing. I recently updated drivers as well but no change. I get slow down when closing a trillian chat window as well. Toggling hardware acceleration did nothing. I'm unaware if audio is being decoded by anything else.
