You can just mount the directory containing the videos and playdam.exe via DOSBox. Then, via the switch -1 you're able to dump all frames of a video as .pcx.
Sound is a different matter, you would probably have to record it separately, import all the single frames and re-synch it.
Here's all switches of PlayDAM:
PlayDAM: Variable-length frame GDV file player : 'Version 2.609'
Orignal verion by Jim Tebbutt & Graham Stone / Gremlin Interactive 1994
(C) Ratt 1994 (DOS4gw)
Usage: PlayDAM gdv_file[.GDV] [-flags]
-i Displays info about the gdv before playing {off}
-f# Fades the picture out when complete (1=slow, 40=fast) {off}
-s# Fades the picture in at the start (1=slow, 40=fast) {off}
-d# Specifies delay in 1/60 secs to hold image before fading/exit {0}
-r# Specifies read ahead buffer size in K {2048}
-q Turns off ALL messages (Allow no sound) {off}
-l Loop play {off}
-a Turn off join fade colour {on}
-t DEBUG run.. no IRQ code {off}
-j Convert 15 to 8 bit (if available) {off}
-b# Skip if Behind (2) {off}
-m Report memory usage {off}
-x SoundCard info. {off}
-c# CD test (#=k per second) {off}
-n Force interlace {off}

-u Switch X<>Y {off}
-p Progress bar Top_bar=Frames_in_memory Next_Bar=Frames_Behind
-8 Use internal code to convert 16 bit samples to 8 bit

I dumped a video from Normality (which is using the same video format) and uploaded a single frame as JPG.
