how to use ifoedit to comebine vob files to make dvd-r

Hi there,
I was reading the various posts about joining DVDs and I have a similar problem. I'm trying to join two full DVDs onto one Disk.
Attempts using both DVD shrink and DVD2one have failed. DVD shrink refuses to see the main title in re-author mode of both disks. I get the following error: "DVD Shrink encountered an error and can not continue. Invalid data in file M:\ROTK1\VIDEO_TS\VTS_01_1.VOB." The same happens with the disk 2.
I get a bit further with DVD2one join mode, except it doesn't register the whole of the second dvd. You join it, and it's not the whole of the second disk anyway, and the picture occasionally blips. This is Return of the King which I downloaded. Playing the film on normal playback is perfect, but I have a worrying feeling that only Ifo edit will only rectify the problem. I know nothing about it. But I think DVD2one and DVDshrink are confused about the vob file nos being the same on both discs. Is this what the problem could be?
If so, is there a straight forward guide in IFO editwhich can help me re-author these two DVD disks into one perfectly playable DVD.
Thanks

 

Fasfrank...............Hi Frank thanks again...yes Minion had told me about this complex method...which does work but is very time consuming....thanks for your suggests....Happy Holidays and Spring to you and yours...Tom

 

Dwayno.....Tom here.....i don't know as much as some of these other guys who are really sharp...the only thing i could think of is "do you have the latest version of DVD Shrink (v3.1)??? perhaps that would help.. lol...........tom

 

Hi Tom,
Yes, I'm running the latest version of everything.
I've decided to give up on this one. I have the full film which is perfect except that it spans over two disks. I just wanted one seamless film. Maybe I shouldn't moan, at least the quality isn't compromised.
Thanks
