A new Old Grey Whistle Test dvd release includes Tom Waits' 1977 performance of Tom Traubert's Blues. This 3 disc box is scheduled for release on August 29. It's not listed in the BBC Shop yet, but it is available on Amazon.com
Play.com lists a Tom Waits dvd, scheduled for release for November 6. No further details are available, but as this is the only source for a new release, it seems highly unlikely this will be an "official" item.
