I saw a cd-r recorded dvd files format in it and able to view with dvd players? Can someone tell me how did they do this? I try using nero to burn dvd format into a cd-r which is possible, but can't view. Drag and Drop can't view it too...

Im rather sure you didnt see real dvd-video file (VOBs) playing from a CD-R
But there are two possibilities:
DVD Player is MPEG-4 compatible, and files on CDR were in that format
CDR was actually a VCD or SVCD or CVD.
The latter format is fully DVD-compliant (if used with 48k audio).
'Course you can have VOBs on CD-R! That's what's called "miniDVD" or "DVDonCD" or "cDVD".
I have a couple of homemade ones (mainly for testers) in my living room right now, as well as a pressed one from Sonic Solutions.
You just have to make sure that whatever burner app you're using understands that even though the media will be expecting "Mode1", that it should put "DVD Mode" on it instead (or rather looking the other way--the image is expecting DVDMode, but you're going to put it on the disc in Mode1). Everything will be alright, of course, as they're basically the same.
The ability of a player to work with this is usually a firmware and CD speed issue (you can't give it regular bitrates; need to keep down to ~2.5-3.5Mbps or it skips).
The other things DereX888 said could be true here, though--you might have actually seen something else.

But it does play on 100% of software players.

I think 15% of standalones is a great exaggeration.
Perhaps even a 1% would be too optimistic as well.
Thus, IMHO, "miniDVD" is a strictly computer format.
I'm pretty sure it's a CD-R with vobs inside the VIDEO FOLDER.
So all I need is the application that understands it? Which program can I purchase?

Well, here go some facts about the "well-known" cDVD:
-- outside of the U.S.A. (and outside of Europe too, I believe), the quantity of standalone DVD players that do support miniDVDs is not that small;
-- if you are ready to accept inferior quality, miniDVDs can contain up to 2 hours of video;
-- WMP 9 plays not only miniDVDs, but also VIDEO_TS directories recorded on the hard disk;
-- LG 7352N handles non-DVD-standard video resolutions (480x320, 528x400, 576x432, etc.) without a problem;
-- DVD Lab Pro accepts creating non-standard DVD-video stuff, with or without complaining about that ^_^ ;
-- IIRC, some ancient DVD players were unable to play CD-Rs, but were able to play CD-RWs;
That's all for now.
