CD-R vs. CD-RW

[speedy726]

I have a SVCD movie on a CD-R that plays fine when I play it through my Pioneer 440. My friend wanted a copy so I decided to create an image of the whole CD-R using Paddus Discjuggler and then (to test whether it will work) burned it on a CD-RW. Now, when I played the CD-RW through my Pioneer 440 [which does play CD-RWs], I noticed 20 minutes into the movie about a 5 second interval where extreme artifacts or huge pixels would appear and disappear and sound would *screech*. I would need to fast forward the movie to make it move again. My question is: Is it because I made it using a CD-RW that the artifcats appeared or is it the implication of imaging a SVCD disc. [Perhaps I should use Nero's imaging ability?] In any case, what is the best way to duplicate an SVCD so I can give my friend a copy that is exactly like the one I have and does not contain any messed up scenes. Thank You!

in my opinion
i would use CDRwin to make an image of the disc [.bin+.cue]
leave the settings where they are when you open CDRwin

also you may want to SLOW DOWN the re-burning of the disc image
try 1x or 2x - i know it sucks but ya gotta do what ya gotta do

perhaps the CD-RW has reached the end of it's life [usually 1000 burns]
that is considering if it is a half decent CD-RW

for me this method for reproducing ANY DISC IMAGE has been faithfully consistent over the last 5 years

i just thought of something (eureeka), what if I just copy the mpg file from the mpeg2 folder on the SVCD disc? Can I just use that mpeg file to make many more copies??

[blackestflag]

you COULD do that but then you would have to recreate all the other directories and go through the vcd creation process again

use cdrwin to make a .bin.cue from the WORKING disc and then you can burn as many copies as you want from the .bin.cue

Another problem I have seen, only 74 minutes
CDRW disks are readable in my DVD player.

80 minute CDRW disks appear to cause problems,
either not reading, or stopping midway when playing.

OK I"m confused couldn't you have just copied the movie disc to disc using nero or some other program. why all the extra stuff Just curious.

right on vcd4me...just do a cd-copy...

@speedy726-I have a question...how did you erase the CD-RW? When I erase mine using the quick option in Nero, I almost always (75% of the time) have a lot of skipping and giant portions of green and blue blocks and it generally just fu%$s up in my Sony player. When I do a full erase, no problem. Try doing a full erase (assuming you were doing a quick before).

I've had problems with both CD-R and CD-RW when I burn them at their maximum rated burn speed and play them on a Pioneer 343 (Kodak, HP, Memorex, GigaStorage tested). I get much better results burning at no more than 75% of rated burn speed.

It appears to me that read errors in the player cause a reread of the CD and this delay causes blockiness. So IMHO do a slow burn .
