What options should I have for files bigger than 2G ? (cdrecord and mkisofs)

[Gregoire Favre]

Hello,

I wrote a small wrapper script to burn DVD, it works very well for files
smaller than 2Gb but the big one are readable in a "funny" way : if they
are video files for example, mplayer can plan them, but not seek in
those files ???

Could someone with more knowledge tell me what I should change in my
wrapper ?

Thank you very much,
