Note - KEEP YOUR ORDER ID NUMBER. You'll need your order ID number to view the clips for the first time, and you'll need it if you ever need to re-acquire a license after you change computers or move the videos to other hard drives. Some of our videos will tend to be quite long, especially our full-length feature matches. Our earliest videos will be 640x360 widescreen, but shortly after our first few releases we switched to 856 x 480 widescreen, which is a good trade-off between file size and HD quality. Our newest releases are 1280 x 720p HD (High Definition!). All videos are WMV files, and are ONLY compatible with Windows Media Player on Windows Operating System. (Mac users can only view clips if they are running a Windows Operating system on their Mac Hardware). Please take the compatibility test at ct.drmnetworks.com to ensure you can play our files, as refunds will NOT be issued if your computer is not compatible - Thank you.
