I am attempting to use DVD2SVCD to create a DVDR and I have a question for the aspect ratio?

I am currently trying Scarface which is widescreen, doesn't that mean 16:9. The title of the DVD is Scareface_43_Letterboxed and when I load the IFO of the main movie into DVD2SVCD it selects 4:3 for the aspect ratio.

I thought that widescreen was 16:9 and full screen was 4:3.

If I load the IFO with IfoEdit it also says 4:3.

Should I change this or leave it?

If I leave the aspect ratio as 4:3 won't DVD2SCVD remove the black borders?

Any experienced comments are appreciated, Thanks.
