Hi as Kastubh pointed out, VCD are not in ISO 9660 format. It doesnot matter if your Data is on A regular CD-R or CD-RW, Functionally both will work same while reading, the only difference as we all know is CD-RW can be erased and re-used. > Why should this increase the size?

Wait, don't fire at me so soon, I'll > search the web for this now! :-D Reason for the incresed size of the image -- Data is put on a CD in sectors and tracks-- the usual ISO9660 format, that we use to store data regulary, uses a sector size of 2048 byte + few more bytes for error correction and detection (ECC/EDC) But the mpeg data -- or the ususal .dat file on the vcd which can be roughly reffered as the second track does not uses this the error-correction and the sector size used is 2324 byte which give you approx 14% more space to store data. Hence when size shows up actually more than the capacity indicated on the CD. By the way, the above only happens if you create a VCD not a Data CD, if you try to dump a .dat file > 700 MB it will not be able to write to the CD. > (okay, now I know iso9660 won't work!

AFAIK you wont be able to mount the VCD-image as such because its a raw image and not a ISO9660 format. If you are intrested in playig the movie, after mounting the image, dont bother, use mplayer. ie mplayer image-name. Mplayer can directoly play images of VCD ;) > Kindly help me figure out this thing, and correct me whereever I'm wrong! :-) > > Regards, > Kapil > If you are really intrested in understanding and playing around with VCD's get VCD-gear, these are tool for creating and ripping VCD's. ~~~~~~~~~ >From Dexter http://dexter.ionichost.com "Life though is clear, people still want to see colours" -- ______________________________________________________________________ Pune GNU/Linux Users Group Mailing List: ([EMAIL PROTECTED]) List Information: http://plug.org.in/mailing-list/listinfo/plug-mail Send 'help' to [EMAIL PROTECTED] for mailing instructions.
