Hmm - strange.
I posted a letter here a while ago , but now its gone. OK ! I´ll do it again.
I called to my friend today and he asked from his friends, who work in video production company.
HD mp4 video runs mostly on CPU (codecs). Unless, you use special HD video card, that has codec in harware. So the problem is in here. The first question was - what operating system You use.
Linda - what is Your OS ?
Let me quess VISTA !?
I have Vista (32bit). The guys from video vompany told to forget about Vista when working with HD video. Use Mac, Linux or WINDOWS XP.
So tomorrow, when I get home, I will first try to install the codec they suggested (core AVC), that must be the best HD video codec and if that does not help, then install Windows XP as secondary boot to my PC.
