Sony Blinks, Issues DVD Recall

In a surprise move, Sony has (somewhat quietly) announced the discovery of a "problem" with some of their recent DVD releases that prevents them from being played on some DVD players.
They are offering to replace anyone's discs that has experienced problems with playback.
Strangely, a search of Sony's own website reveals nothing about this.
Apparently, it is being reported only in the trade publications like Video Business.
In an official statement, the company said,

“Recently, an update that was installed on approximately 20 titles was found to cause an incompatibility issue with a very small number of DVD players (Sony has received complaints on less than one thousandth of one percent of affected discs shipped). “Since then, the ARccOS system has once again been updated, and there are no longer any playability problems.”

Anyone who had purchased one of the discs and has experienced problems playing it may receive a replacement disk free of charge by phoning 800-860-2878.

I am continuing to read with interest, Mick B's blog about his ongoing discussion with Sony over this.
