We are talking the same thing. You just call it something different. With the factor 1.41 you can calculate that 704 pixels resolution is equal with 703/1.41=497 lines of resolution of DVD. Just exactly the same as my calculation!

Where have you got the value 320 lines of resolution on VHS?
As I said IF VHS resolution is 240 lines, it corresponds to 320 visible pixels. IF it is 320 lines of resolution then it corresponds to a resolution of 427 visible pixels on the screen. If 8 % of the picture is in the overscan area of the TV then you'll need 464 pixels resolution. But this is no standard capture format. SVCD resolution is 480 pixels width and should be sufficient in your case (with your equipment and your eyes).

I thought VHS resolution was around 240 lines, and SVHS 400 lines but this may be wrong.

You can do the opposite test. Feed your VCR with half D1 source and record and then compare the result with a VHS recording from full D1 source. I can't see the difference on my equipment with my eyes when I play the VHS copy...
