1MOV files since Quicktime version 3 are not supported by Active Movie, which ThumbsPlus utilizes. However, you can download and install the free Quicktime Alternative codec. This enables Quicktime movies to play in Windows Media Player, which will subsequently allow them to play and thumbnail in ThumbsPlus. You can download and read about this codec here:
