With OS X in general, various of the GUI tools are wrappers around the command-line tools, or both the GUIs and the command-line tools use the same frameworks. Common code and all.
At the lowest levels, some DVD players are also sensitive to the particular media, with DVD-ROM and DVD-R and DVD-RW being accepted by some, some happy with DVD-ROM, DVD-R, DVD-RW, DVD+R and DVD+RW, and some sorts of media simply not being accepted by some players at all.
At the level of the DVD disk structures, dumb-as-a-post video players expect specific volume structures on the DVD disks, and ISO-9660 volume structures and not HFS+ volume images, and specific filenames. It's easy to get this stuff wrong — voice of experience, there — and sometimes poking at the created volume to see what's really there is the only way to figure out what went wrong. Sometimes the command-line tool or the GUI tool uses defaults that are... unexpected.
Installing some add-on open source can involve some fairly convoluted command syntax. One in particular I sometimes use is very flexible, and gonzo cryptic.
More practically, I've used bash scripts to generate various sorts of images for specific targets, and there are undoubtedly some add-on GUI tools that can make this stuff easier. Depending on what you're up to, the Apple iMovie stuff can work well, and the Apple iDVD stuff looks to be very close to what you're working on.
All that written, there are ways to burn "coasters" with both the GUI tools and with the command-line tools.
If you have a specific Finder sequence or requirement, details might help sort out what happened. (That could be due to either the volume format created, or something with the video filenames, but I'm not at all sure...)

If you have the proper video image format then it should make no difference. I've burned video DVD's using images created by iDVD with Finder and have no problem playing them in 'dumb' DVD players.
As MrHoffman wrote if you supply more detail of what you did, how were the images created how did you burn them, etc. it might help to sort it out.

thank you for the help...
so what i'm doing is i use dvdauthor to author the dvd (audio_ts and video_ts folders) and mkisofs to create the image (dvd.img). if i then follow up with:
hdiutil burn dvd.img
it will burn a dvd that will play in my standalone player. it will also "autoplay" in dvd player on mac. now if i take that same image (dvd.img) and mount it and drag the audio_ts and video_ts folders into a finder window and burn a dvd that way it appears to be ok (meaning the file structure) but it will not play in my standalone player and it will not autoplay in dvd player on mac...
i hope this helps explain it better and thanks for your time,

As I think about it and look at the iDVD help pages the .img file needs to be burned using Disk Utility not Finder.
You can't manually take the _ts files and burn them. While it looks the same in Finder the format on the DVD is actually different and will not work in a DVD player (as you found out).
There is one catch. If you're burning dual layer DVD's Disk Utility won;t work. In that case the DVD needed to be burned right out of iDVD for the layer break to be put in correctly.
So your choices are to keep using hdiutil or if burning single layer disks using Disk Utility.
