Indeed, it is a sad day indeed. As much as i dislike HMV for it's service, there are only a few places left that sell DVD's, CD's and stuff. Thats IF HMV actually close, who knows they may not close.
But didn't a Comet director join HMV well before Comet closed, maybe he did the same damage. HMV is a dying breed, and it's been said that online media for music has truly taken over. Places like Amazon have the balls of the market now.
