Only dvd-roms can read standard DVDs. I'm not sure if you need a DVD+R/DVD-R/DVD+RW/DVD-RW drive to read DVD-Rs. (Most likely not, and that most modern DVD-ROMs should be able to do the trick there.) However, standard cd-roms or cd-rws won't be able to read your dvd-r.

Let me clarify the above post:

cd-rom - plays regular cd-roms
cd-rw - plays cd-rom, writes to cd-r, writes to rewritable cd-rw

dvd-rom - plays cd-rom, plays dvd
dvd-r - plays cd-rom, plays dvd, writes to dvd-r
dvd-rw - plays cd-rom, plays dvd, writes to rewritable dvd-rw
dvd+r - plays cd-rom, plays dvd, writes to dvd+r
dvd+rw - plays cd-rom, plays dvd, writes to rewritable dvd+rw

For some reason there are two dvd writing technologies available now. DVD-R/RW and DVD+R/RW. It's too early to tell yet which one will be standardized in the future for dvd technologies.

I played it in a DVD-ROM

Not all dvd-roms can play dvd-rs. Some do, some don't. Many of the older models don't.

Maybe you did not 'close' the DVD after you were finished making it?
DVD-Rs play fine in my Dell laptop. I don't know what kind of Dell you have, but I have an old Powerspec with a DVD drive, that I bought back in 1999, and that plays DVD-Rs fine as well. Hopefully if your computer is newer than this, it *should play the DVD-R.
