Sony DVGate 2.6 - as found on most (but irritatingly, not all) Sony Vaio machines.
I'm uploading this because SonyStyle assured me that ALL Sony Vaios included this software, only to discover that my brand new machine didn't. However, it was found that the install packages from the recovery discs of another Vaio worked fine.
So here they are. Everything you (should) need to get DVGate up and running on your Vaio if you, like me, were unlucky enough to not get it bundled.
