more than one video in a node

not possible with the current video module version.

there are however some patches that could be used for this ... for example the video filter patch
(see this bug tracker queue)

For such purposes, you may want to try the embedded media field - http://drupal.org/project/emfield - which does just that (allows you to attach one or more videos to a node). While the video module is a more robust and complete approach, the embedded media field works well if all you want is to attach videos to a content or create nodes with one or more external videos (youtube, google video and many other sites not supported by the video module). I actually use both modules...
