It's known Linux isofs deficiency. I personally recommend to stick to 
files smaller than 2G-1 (see 
http://lists.debian.org/cdwrite/2003/12/msg00101.html for example) to 
*ensure* maximum interoperability. I realize that it might be 
inappropriate in some particular situation such as is. If you absolutely 
must have files larger than 2G master with -udf option and mount volume 
as udf instead of isofs. A.
