I am a BP220 owner and have had the "unit suddenly becomes unresponsive" problem referred to above, ever since I have owned it. The "solution" offered above is not a fix, but a half-assed workaround. -- What if almost every time you wanted to use your computer to get on the internet, it suddenly froze up and all the manufacturer offered as a solution was to unplug it, wait a few seconds, and then plug it back in. -- Or if your car always suddenly died after driving 50 miles, all the manufacturer offered as a solution was to disconnect the battery, wait a few seconds, then reconnect it???

Since LG has admitted it is a "known issue", then there should have been a recall to either repair or replace the devices for which the problem exists.
