I'm thinking of upgrading all of my kids DSLites to DSi's (four of them).. Right now they all have Acekards, which work great.. They would like to be able to also watch movies on their DS, so I was thinking either iPlayer or Supercard DSTwo.. Our whole video library is all XVid.. The iPlayer seems to be able to play XVid with no problems.. Can the DSTwo play vidoes as well? Is there any reason to get the DSTwo over the iPlayer?
