Anyone feel like helping me out? I'm trying to improve my DVD detection
routine. Instead of checksumming the entire disc I am trying to checksum
just the first lil bit of the disc. It's much MUCH quicker. I'm just
trying to get an idea of how uniq this method is and how reliable it is.
I use this so that my ripping/playing software can detect the proper name
of the DVD without needing to be entered by the user. Pretty much works
like cddb does for cd's. Probably is some standard way of doing this but
I've yet to find it so I make up my own method.
If you're using Linux the easiest way to checksum a disc is to put it in
the drive and then do 'head /dev/dvd | md5sum -'. Here is a tab delimited
list of a few movies I had sitting on my desk. Checksum, title, length,
and rating. Does anyone have the same discs and get the same checksum or
have a different disc that returns the same checksum?
