DVD player not working with superdrive on Mavericks

Question

Hi, I have installed Mavericks on my MacBook Pro. I have two SSD HDD and no internal optical drive. I am using the Superdrive externally through USB. It worked fine under Mountain Lion. Right after installing Mavericks when inserting a DVD DVD Player came up with the message "Initializing error on drive". Hope anybody has found the solution. Ca't find any answers anywhere.

Hooray I got it working!!
Vishva's advice was correct but incomplete, the important part that was missing is that you need to replace ALL occurences of the word 'internal' with 'external' when you hexedit the file he recommended, I found the following web link with the full instructions.

Incidentally, when I tried to edit the file directly I was given an error saying it was read only and wouldn't allow me to edit it, so what I did was save the file to a new name, make all the edits and then copy the new file into the correct directory, then using terminal issue the following commands
cd /System/Library/Frameworks/DVDPlayback.framework/Versions/A
then once you are in the directory containing the old and new framework file you need to copy the old file to a backup name for safe keeping, so issue the following command:
sudo cp DVDPlayback DVDPlayback-backup
Then rename the new file you created (replace {yourfile} with the name you stored it as!) to the live one using:
sudo cp {yourfile} DVDPlayback
If you list the files in this directory using the following command you should see all the files and their ownership and permissions:
ls -alh
all files should be owned by 'root', if the newly created file is owned by your username, in my case it was, then you can change its ownership by typing the following:
sudo chown root DVDPlayback
I then exited terminal, rebooted just to be on the safe side, and hey presto the DVD drive now works perfectly, shame apple didn't put something in place in mavericks to check for this, maybe they will in future updates...
Hope this helps anyone having the same issues, and thanks Vishva for pointing me in the right direction!
