problem watching High Def Videos

From Last Week i am having some problems while watching videos.

The problem is both in the audio as well as the video.
Are there any tests to determine the problem?

I am using Km Player to watch the videos. They are all HDTV videos i downloaded from torrent

what is your computer specification?
what is the version of kmplayer, i suggest you to use other players as jetaudio,..
after all, what was the movie?

We download a lot of TV shows and although they are quite often labeled as HD that is not what arrives. Those network downloads seem to adjust for the available bandwidth. When we download from Dish, quite often it will start two downloads, one fast and nasty 120-200MB and one HD 750MB-iGB. I know little about video but I have the feeling it takes huge bandwidth to get true HD. We usually try to clean them up a bit with conversion but I suspect that is really mostly a case of "garbage in, slightly less smelly garbage out".

buddy the problem is with your player, or maybe with your computer spec. tell me your cpu, graphic card and ram values, then check other player. get jet audio from the link below:
JetAudio

And you didn't tell me the name of the movie,if it is good we get that too

Chip Type: Intel(R) HD Graphics Family
DAC Type: Internal
Adapter String: Intel(R) HD Graphics 4000
Bios Information: Intel Video BIOS
Total Available Graphics Memory: 1158 MB
Dedicated Video Memory : 64 MB
System Video Memory : 0 MB
Shared System Memory: 1094 MB

you dont have a high system, using win xp will help u to reduce your graphic memory usage and u can do better.
also check your startup programs and close any non-necessary programs,(use "msconfig" in run) and check ur system for viruses...
