There is also another download related bug in VC.

I have a 8 GB SD card and when the free space on the card was almost down to 4 GB, Videocenter did stop downloads with "out of memory" messages when hitting the 4 GB boundary.

The solution was to put some more data on the card so I had a bit less then 4 GB of fres space. After that VC didn't give the out of memory error anymore.
