DVD Header patch works at any resolution?

I have several TV caps at 640x480 using Leadtek Winfast 2000 Deluxe. When I copy the files onto DVD as MPEG2, my Apex 1200 plays them perfectly. When I author these files using the DVDPatcher method (with 48kHz of audio), the DVD does not play correctly. Only part of the image shows up on the screen and the video freezes after a few seconds while audio keeps going. I played it on the PC using PowerDVD and it plays, but only part of the image shows up. At first I thought it's a limitation of the Apex, but since PowerDVD also plays only part of the screen, that leads me to believe it's the authoring. I authored with Ulead Movie Studio 2.5SE, patched each resulting VOB file back to 640x480. MPEG files have bitrate of around 3200kbps. Is there something else I could try? Thanks.

why not cap at 720x480?No need to patch.

I thought 720x480 is overkill for regular cable TV, and my system isn't fast enough to comfortably capture at 720 at a high enough bitrate to make it worthwhile. It has no problems at 640x480 at 3200kbps which I though is adequate. I'll probably go with 352x480 just for convenience. I use Ulead Video Studio to cut out the commercials, and on output it converts audio to 48k without reencoding the video so the speed is not bad.
