Downloading popular files from T3 sourses is a risky business. I suggest you try for a Modem or Cable source, and try to find files with different bitrates from the corrupt ones or with possibly a couple of seconds difference in time. This will help ensure you do not get the same files again.
The download will take longer but you have more chance of getting a good file.

BTW it is actually against forum rules to mention the names of items you are trying to obtain so in future it is best to keep names out of it
