Finally I tried also the second trailer (High Bandwidth 720p Stereo .WMV 81.1Mb), I was curious :lol:
This trailer has 720p resolution and a bitrate of 8Mbps, duration 1:36 (min:sec) and at the end of the video I had 250frames dropped (I lost circa 8seconds of video on 96seconds -> ~9%)
It's an high percentage, but my PC is not meant to be used to play HD contents
and don't forget that the video is progressive and I have other applications running on the background :D
I'm satisfied by my PC behaviour :o
Probably on adicoto's 3GHz celeron there will be 0frames dropped
P.S.
My VGA is a GeForce4MX
