| DVD+R and DVD-R are the formats used to record onto the disk, so the hardware has to be able to record in those formats. Think of it as Betamax and VHS.
Most DVD writers are dual format "DVD+/-R" format writers anyway, so you should be able to specify when burning the disk which format to use.
Unless you're putting over 4Gb worth of movie onto a disk, there really is no need to use DVDR - just put it onto a normal CDR as an SVCD which has the same resolution as DVD!
Just about every single DVD player will support SVCD as it uses the same compression routines (MPEG4) as a DVD does, so there's a much better chance of success.
You can get about 40-50 minutes of DVD quality movie onto a single CDR using SVCD, or even more if you compress the movie but you will lose some quality.
Software like DVD Shrink is ideal as it does everything for you. |
