Why can't DVDs authored on CDRs be read on DVD players?

[tyee]

Anyone know why this is. Is it because of the disc itself or the authoring program? I tried playing a DVD authored on CDRW in a sony and pioneer player. The sony won't play it but the pioneer does according to the front panel display (time increments) but on screen, there is nothing.

2 reasons mainly:

1) media recognition. Most players check the type of media you insert and load the appropriate player software. So.. they detect a regular CD, but the fileformat is neither CD audio, VCD/SVCD so they're stuck... almost no player actually recognices the format and start the dvd player software

2) the built-in drive. Usually these drives are really low performance if you compare them with PC drives. Normal DVD players can play CDs at max 2x speed, just enough to play an SVCD. Hence, if you have a higher bitrate than the SVCD max the player can't keep up with the movie.

Eventually recordable DVDs will make miniDVDs obsolete anyways. A media price of lower than $3 is already a very good bargain.

Mustek 520 and 560 plays minidvds on cdrs without any problems. These dvd drives are cheap and very good also. They play mp3, dvd, minidvd, svcd, xvcd. You can make it regionfree with just your remote controll.
They even play all sorts of media cdr/cdrw and most dvd r media to.

I got one myself and I can say that the quality is very good.

Best buy you can every make.

Most people has to pay about 12 dollars for a dvdr. And that is way to expensive. Calculating in all the time it takes to make a minidvd on dvdr it's simply just not worth it for us. But on cdr it is. Because a 100 cdrs costs about 27 dollars. And one dvd 12 dollars. muhahaha.

Teddy,
I read that you use a Mustek to read miniDvD. How do you create them. I have a mustek too? I would like to simply cut and copy the vob's on the CD-r no matter how many cd-r's are needed.

Sifran: it's not that easy :) I made a couple of minidvd's which work great in my afreey ld-2060. Picture is better than svcd and sound is the original ac3. I guess using robshot's new method of encoding with cce (I used rempeg back then) would get us very good quality on 2-3 cd-r. Maybe just 2 with 90/99 min cd-r.
I split the movie in a number of vob's (think you can use smartripper for this) and then demuxed ac3 and m2v from them. Ac3 have to be "ac3fix"ed sometimes. m2v files you can re-encode with whatever you like.
Fire up maestro and author the cd-r using the reencoded m2v and ac3.

Easy and inexpensive on cheap cd-r media.

Actually dvd-r media are getting very cheap almost the same price as 7 80 min cd-r here. I will be getting a burner soon and then bye bye minidvd. :) I can have 2-3 movies per dvd-r not needing to change cd in the movie and cd-r is probably a lot more compatible than minidvd will ever be

Just a question.
Why don´t you use the "sysygy" player the comes with maestro?
Its a briliant player, and designed to play from CD-R´s.

??? a standalone player cannot use this player?
