We watched The Wire on TV up to the end of Season 2. Then we got impatient and bought the DVDs. We bought Seasons 1 and 2 even though we'd seen them as we intended to watch it again.

So went to watch The Wire Season 2, finally, and our DVDs were rotted. Never played, never to be played.

Luckily Warner Australia (who distribute HBO in Australia) have a replacement disc policy. Sent them the discs with an explanation letter (where did you buy it, how doesn't it play?) and they'll test it. I presume as long as it isn't covered in scratches (that is, obviously destroyed by you) they'll replace it.

We got our Wire Season 2 back today. Hooray!
