hello everyone,
currently i m working on remastering of Knoppix 4.0.2.
i have created my ISO file successfully and also
tested it with cheatcode using
knoppix bootfrom=/dev/....iso
and it is working fine.

but, when i burnt this ISO file on DVD,
it is not working..
i mean booting process stops abruptly...
without any error messge...
actually it boots up to
inital booting splash screen..
but when it reaches to initializing system configuration,
it stops there...
after sometime it even stops reading from DVD...
and eventually no Desktop gets loaded
even waiting for long....

it also shows some error messages during inital booting process..
like, "LOPP is in use...
can not mount CLOOP..."
and also,
can't find "localtime file in /etc/"

plz, show me way out of this....
thanx in anticipation...
