Hi,

Is there an easy to get the starting physical block of file?

I am writing an application which is manipulating the block
size of for reads to a cd9660 cdrom. 

In a nutshell, I am reading a file in a VideoCD whose block size is
2336. However, whith normal reads the system returns 2048 blocks.
I am able to program the cddrom drive and tell it that the block size
is 2336 . So far I can  read a movie and display in my system however my
starting block location number for the file is fixed right now.


	Tnks,
	Amancio
