full HD video is lagging while being played?

Question

Both of my desktop and laptop are DUO CORD. I downloaded
some full HD clips of Sanyo HD1000 and they are always lagging while I play them.
I was told ever PC with fast CPU even can not play smooth full hd clips.
what is H.264? If I download it, will it help the full hd clips run well?

Answer 1

I play full HD (1080p) clips smooth on a laptop with Core2Duo & 2GB RAM. Not even using hardware acceleration (i.e. not using the graphics card).

For a tutorial on playing HD clips, have a look here:

I use:
Haali Media Splitter -> http://haali.cs.msu.ru/mkv

ffdshow -> http://sourceforge.net/projects/ffdshow-tryout
+
Media Player Classic -> http://sourceforge.net/projects/guliverkli2

Hope this helps

i doubt it, it's simply a matter of ram not processor speed at that point. you can get them to play right but your're going to need a good graphics card and 4 gigs of ram.
