Larger MPEG files

[srinathtk]

Dear Friends in the forum,
I had few 700MB VCDs with movies on it. I copied all the contents of these
CDs on to my hard disk and rrerturned them back.
Now when I wanted to burn these into VCDs, I found that
the .dat file sizes are bigger then 700mb say 739mb or 725mb
or so. How is this possible? How this 725mb fits in 700mb cd.

I wnated these movies to be played on a VCD player. If it is copmuter,
I would have used Div x to compress these files.

Please help me to make VCDs out of these files.

Well, a 700 MB CD has not 700 MB of space, it has about 800 MB. Audio and Video CDs use the full space, so you can also burn a 800 MB MPEG file to CD as video cd or 800 MB of wav files as audio CD.
Data CDs fill a sector on the CD not only with data, but also with checksums and redundant data for more security. Because of that security backup you can only use 700 MB of the space, the rest is being used for the redundant data and checksums automatically when you burn a data CD.

That is also the reason why you can burn a data CD with 52x no problem but for a music or video cd it's better to use 4x or 12x, not more. It's because of the missing "defect management".
