How to Convert Your HD-DVD Discs to Blu-Ray

eldavojohn writes "Are you one of the few who boarded the HD-DVD Titanic ship headed to the bottom of ocean to join BetaMax? Fret no longer, friend, simply convert those and pretend like you never invested in the wrong technology! All you need is a Windows machine with a fast processor, an HD-DVD drive, a Blu-Ray burner, 30GB of free disk space, at least, though 40GB or more is recommended and an internet connection to download the software! Or you can sit and be the crazy guy who continues to argue that HD-DVD is the superior technology whether it's true or not."

60Hz (depending on the power source) hum in audio equipment is quite common, and not actually a sign of a bad ground. Removing the ground pin is the wrong way to fix it.

The hum occurs because of an amplified ground loop. A ground loop is formed when the output of a grounded audio device is passed into an amplifier connected to the same ground. Shielded cabling will then ground the chaises of the signal device and the amplifier together, creating a closed loop between the devices and the electrical earth. This closed loop can then build up a 60hz cycle, I believe through induction with the power mains, but have not found a definitive answer. Normally this cycle is not enough to be electrically significant, except it is passed through an amplifier along with the desired signal. Removing the ground pin from one device will indeed open the circuit, preventing the ground loop from being able to cause a hum.

However, as you surmised, disconnecting the ground from an electrical device can be dangerous. The accepted way to open the circuit is by breaking the ground connection between the amplifier and the signal device, generally at the amplifier rather than the signal source. Doing so will essentially eliminate the effectiveness of the cable shielding, but will also eliminate the loud 60hz hum which is generally much louder than any electrical interference you will find. However, the electrical ground of your electronics will not be compromised, saving the equipment and operator from damage in the case of a malfunction.
