Title:
  [Acer Aspire 5749] Totem playin DVD fullscreen causes CPU to overheat

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I play a DVD in full screen mode on my large monitor (2560 x 1440
  pixels). The CPU temperature quickly rises from about 50 degrees
  Celsius to 80 degrees, causing the fan to run at full speed (which is
  noisy and irritating). Running "top" shows that Totem is only using
  about 25% to 30% CPU. CPU is running in Conservative mode at 800MHz
  (36% of full speed).

  This behaviour does not occur in full screen mode on my smaller
  monitor (1280 x 1024). Neither does it occur when I use another media
  player (VLC) to play the DVD full screen.

  WORKAROUND: Use VLC.
