Video category is wrong !!!

If they are genuinely in the wrong category then change them, but how do you know they are?

Looking up the first one I get the following information, which suggests it is correct:

The Ark of Truth was released as a Region 1 DVD release on March 11, 2008. Sky One broadcast the film on March 24, 2008, to be followed by the Region 2 DVD release on April 14, 2008.

Stargate: Continuum is a trickier one - it got its first broad release on home media but did premier at Comic Con a few days earlier. So the video assignment is not unreasonable.

Prison Break: The Final Break does seem to be a TV movie, although it'd be worth doublechecking the release dates.

For Payback :Straight Up I can't find enough information to call it.

It might be an idea to start a thread on each of their forums asking for clarification - a few of those may be wrong (at least one is correct), but for most there isn't really enough information around to come to a decent conclusion about it. If you know more, then feel free to throw it in.
