I apolgise for all the questions in the past two days guys. Feel free to delete the two posts I created. Basically im trying to do to much in a short space of time. Need to take short steps etc.

Firstly, I need to extract the audio using the method described in this thread.

With regards to Step 3:

It mentions converting 4x3 interlaced video to 16:9 anamorphic... (Im doing Attack of the Clones...do I ever need to do the step of amending the AviSyntch script? or is this for movies which are not anamorphic?)

Basically Iv followed this to the letter. But I believe my version of tmpgenc is a different version.

When I import the video I get the following options:

Pixel 1:1 (Square Pixels)
Pixel 10:11 (NTSC 4:3)
Pixel 40:33 (NTSC 16:9)
Pixel 12:11 (PAL 4:3)
Pixel 16:11 (PAL 16:9)
Image 4:3
Image 16:9
Image 2.21.1

It also asks me if I want the video mode to be progressive or interlaced. Iv kept it to progressive because the short preview indicates no interlacing (black lines etc. so thats fine by me)

But which of the above settings do I use? Choosing Pixel 40:33 (NTSC 16:9) puts black bars on the top and bottom. If I did this though wouldnt it lose its anamorphic properties?
