Some of the downloads I get to viedo clips are around 100Mb and will only show that they are only a minute long, but when I click on the middle of the clip time bar to forward the clip I see other parts of the clip that are not in the minute of continous play. My theory is that I may need a decoder of some sort in order to play back and register the time of the full file.

If anyone has a clue as to what I am talking about please reply

Thx
