Hello All,
Here, we've an IBM Thinkpad a21p.
We found that DVD playback and MPEG-coded video playback in general
suffer from a serious "aliasing" problem ("steps" on the edges of
objects).
This is very visible if you playback at 320x240:tiny objects and text
are very affected.
We've tried othe DVD players (PowerDVD, WinDVD), and multiple mpg player
(Real, WMP), but the problem remains and seem intrisic to the video
subsystem of the a21p.
Other models of Thinkpads we've here (a21m, a20p) do not seem to show
this problem, even if the overall playback quality is similar or lower.
When you display the picture on an external monitor, the problem does
not show (no aliasing at all and near perfect playback).
Is it due to the 1600x1200 LCD, is it a msiconfiguration of the software
(we're using the preloaded Windows 2000 configuration) ?
Are other a21p users experiencing the same problem ?
What do you think could be done to improve the quality of the playback ?
Thank you for your help
Didier Martin
