Answer 1

Download virtualdub-mpeg2
http://fcchandler.home.comcast.net/stable/

This is a modified version of Virtualdub
http://www.virtualdub.org

-----------------
Once downloaded extract the files and open virtualdub-mpeg2

Goto File > OPEN VIDEO FILE and point to your dat file.

On the video menu change to full processing mode.
Goto VIDEO and select COMPRESSION. Select a codec to use.
I would recommend XVID (Divx is good too) and click configure
http://www.koepi.org/xvid.shtml

Xvid has a built in calculator so you can calculate the best bitrate. the bitrate will affect the size of the file. higher bitrates mean bigger better quality files. To use the calculator press calc. For the calculator to work best you will have to tell it how long the dat file is in hours, minutes and seconds. Be sure to specify what bitrate you are going to encode the audio too and the size of the disk or 716800 in your case and press OK. Switch from target quantizer to target bitrate by pressing the target quantizer button. when you are done press ok and then ok again.

Now goto the AUDIO menu and switch to Full processing mode. Now AUDIO > Compression. Select MPEG LAYER 3 and then the bitrate you want it on the left. this must be the same bitrate you specified in the XVID codec or your file will come out bigger than 700 MB. 128 or 192 at 44100 or 48000 Stereo is good. If it only gives you the option of 56kbps and lower you must switch to the other MPEG LAYER 3 codec or install a different one and start over.

You can set the interleaving options if you want. Otherwise not

Now goto file and SAVE AS AVI. type in a file name and click SAVE. It will take a while. After it's finished check play it back. if the audio is playing to early or too late you have to start over again and on the AUDIO Menu goto Interleaving and Adjust the audio skew correction setting. You check how it's going to come out by pressing the play button after each adjustment.

Hope that helps or points you in the right direction. It it doesn't search for VCD to AVI converters because that is actually what you are trying to do.
