Resizing videos and creating multiple DVDs in batch?

[DVD_Noob]

I have a large number of HD video files which I want to burn onto DVDs to be viewed on a small screen portable DVD player. Obviously I dont need to preserve the full image quality, and I would like to squeeze in as many videos as possible onto a single DVD with reasonable picture quality for a small screen.

I did come across suggestions of RZ DVD Creator which handles this first part well. However, I have a large number of videos to burn onto a large number of DVDs (say about 10). This poses a problem as RZ DVD requires me to compose the DVDs and burn them one at a time only. With each DVD taking about 2-3 Hours, this is not feasible for me.

What I want to do, is to use a software which will allow me to define the DVD content (video files, menus, shrink ratio, etc..), for all DVDs in one go, and then kick off a batch process to burn them all to ISO images while I sleep or am at work. Then I can come in and burn the ISO images to DVD one at a time, which should be relatively fast.

Can anyone suggest softwares which have this ability? I am willing to spend a reasonable amount of money for the software.

See what video formats your player can handle.
DVD video is MPEG2, but if it can play AVI you can get the same quality in about half the size, for instance. If it can play H264 MKVs, even less.
