新手剛上路，請大大們多多照顧一下　
我在網站上找到了這台DVD可更新的韌體，但以下內容看不太懂，請能瞭解內容的大大解讀一下好嗎，到底更新前和更新後是差別在那裡　 還有RPC模式開關有什麼差別呢 以及要改變RPC模式是不是一定要用到Windows RPC-1 utility 這個功具呢？
還有就是我這台DVD在還沒更新前用DVDINFO查看只能讀DVD -R/RW，那更新過後是否能讀到+R/RW呢？
不吝賜教，謝謝 !!

You can use LtnRPC to reset or disable the Region Counter. Click Disable and your drive will be region free!
- Also, a Windows RPC-1 utility (version2) is available. This utility can turn ON/OFF the RPC mode. When the RPC is turned OFF, the drive will became a RPC-1 drive.
