Hey, thanks guys. I just solved my own problem. Incase anyone is wondering. Here's how I did it. I used Avidemux. I went to the audio drop down menu and clicked save. It's playing in MPlayer right now. This is stuff I could sleep too :D Of course, I don't need anymore speeding tickets. I get adrenaline rushes. I broke 3 bones in the last two months from two incidences not involving cars. I never wrecked while speeding, but I was once put in a 6-cylindar Pontiac G6 after a lady pulled out in front of me, and her insurance paid for it. That car costed me over $100 in gas a week to drive to SAC and back 5 days a week. I walked away from all of it without any permanent damage. I threw a rod in my Daewoo car that flew through the oil pan and busted two big holes in it, wasn't smart, but that's what I get for driving a Daewoo Leganza like a Ferrari. Here's the Pontiac g6 on my youtube account. noobuntu is me.

It can do better, but both videos, it was raining and in that one, I had no straight aways when it was dark. Here's the Daewoo Leganza 02.

You guys ever get speeding tickets, go see the comedian at Funny Bone near Rackspace nick named Arizona. He's got more knowledge than the police on laws of driving, facts, great and funny guy. Best of all, I have a discount on my insurance and no bad driving record except for one speeding ticket a long time ago I just paid.

Here's what I've tried to extract the audio. On other places on the net, I saw the same two commands working for others. Here's the video.

In order to get the video.flv, I did some tricky stuff with wget I found from google that worked! I just wished extracting the audio was as easy. Here's how I did it.
