The links below will attempt to show a Flash version of the videos. Successful viewing will depend on your operating system and browser settings. It is beyond the scope of the current GDRP staff to support any problems you have, but feel free to report them anyway (and include the pertinent information regarding your OS, browser, etc.). Try a different browser, or download the .wmv version to view off-line.
The .wmv versions are better quality, but all of these are what they are, as they were created by the late Peter Prunka, and the source material is lost. Note that Volume One was on a CD, and did not include a video.
Update 12/23/17: Apparently, the latest versions of Firefox will not play the flash version without changing security-related settings. IE, Chrome, and Edge under Windows 10 seem to have no issues.
Volume Two: The Early Years
Volume Three: The G&D Matures
Volume Four: The G&D Complete (or nearly so )
Bonus: The 2010 GDRP Christmas Video
