Ok here is exactly what i've done:

1) Decrypted a DVD made on a standalone recorder using IFO mode of DVD Decrypter to one large .m2v file and .ac3 file.
2) I wanted to reauthor the DVD in Encore, but the video was 704x576, which Encore re-encodes, which i don't want.
3) I therefore did a trick i usually do, used DVDPatcher to patch the M2V to 720x576. This adds a green bar of 16 pixels to the side.
4) I then authored in Adobe Encore CS3 as usual, and it doesn't re-encode.
5) I now have my output VIDEO_TS folder, which has 4 .VOB files, as the size is ~3.6GB. I then take the .VOB file back to DVD Patcher to patch them back to 704 pixels. This works fine with the first two VOBs. However, when i try to add VTS_01_3.VOB and VTS_01_4.VOB, DVDPatcher says "No Sequence Header Found" and tells me to select a valid MPEG2 file.

Now i've used this patching/authoring/patching method many times before without a problem, and the first two VOBs work fine here, so what could the issue be with the second two, and could it be fixed?

Thanks
Simon

This is not an Encore problem at all, but I think I know what has happened here.
You've made a mistake in your VOB files.
VOB files on a DVD-Video disc are broken up into 1Gb chunks, giving you a structure of
VTS_01.1.VOB
VTS_01.2.VOB
VTS_01.3.VOB
VTS_01_4.VOB
instead of one long VOB file for your entire 3.8Gb M2V file.

What you should do is google a free app called VOBjoiner, and stitch the separated chunks into one long VOB file & then try demuxing & patching this.
