Hi, I found a show that I really like that hasn't been on air for years and it has recently been added on Roku. The show's IMCDb's page is missing A LOT of vehicles and the seasons are not on DVD, Blu-Ray or any form of home video. So, I'm willing to add the missing vehicles, but I'm having trouble trying to capture screenshots of the missing vehicles. I tried print screening while playing the show on Roku on my computer and screen shoting the show on Roku on my phone. Both situations ending up having my attempted shots going blank. I also tried Googling how I can do it and I still didn't have much luck. So, if anybody knows how to capture shots of the show on Roku, please let me know. I would greatly appreciate it.
