Putting 700 MB on 74min CD and 800MB on 80 min CD

[zzahir]

I read at this site that we can put 700 MB on 74min CD and 800MB on 80 min CD when we use WinOnCd 3.6+ and I am using WinOnCd 3.7 but I cannot put 700 MB on 74min CD and 800MB on 80 ..Is there anyone to guide me ..

Thanks and Regrads

That's right. However, only for SVCDs and VCDs. For standard data discs, you are limited to the normal 650/700 MB limitations.

You aren't overburning. It is simply that (S)VCDs are written in a different mode. CD-ROMs normally devote part of the capacity of the disc to some fairly robust error correction codes. S/VCDs do not and hence have relatively larger capacity.

For example, it is similar to burning audio CDs. Have you ever checked the size of the WAV files (which contain the raw audio data) for 74 minutes of audio before you burn it on a CD? It's about 747 MB in size! This is all burnt onto a 74 min CD-R without overburning.

Actually, it is exactly the same as with audio cd's.
Even more :
Each (S)VCD has a base track (using 2048-bytes per sector) which are minimal 5MB in size, all following tracks (98-left : each track from track 2..99 are movies) are using the same sector-alignement as which are used at audio-cd's (2352-bytes per sector).
Despite of the 5MB 'lost' of the first track, one can put exact 738MB of video at a 74minute CD and 798MB at a 80minute CD.
Usually one must use ± 1-2MB's less than the actual space of a CD, while during creation of a (S)VCD some CRC-codes are inserted in the video-streams.

Well, it depends on perspective. It isn't quite the same.

Audio CD tracks use up the entire 2352 bytes per sector as audio data. You only get 2324 bytes per sector of user data (out of 2352bytes) for S/VCD in MODE2 Form2 sectors... but that's small potatoes.
