So I'm a Jaguar nut and decided to spend a good deal of money and time getting the best picture from my Jag. Basically I have the Jag outputting 9 pin CGA RGB DB9 converted to modern 15 pin VGA for playing on my PC monitor, and also laterally converted to Component for recording. This video explains it best.

It's taken a lot of tweaking to get everything just right... My most recent Jag vids on YouTube are what I think is the best I will get quality wise. I record in component 480p, and while technically not HD, if you make the YouTube video full screen and 480p, it's super clear and you won't even really know it's not 720p HD... Not only have I enhanced the visuals, but the audio is also enhanced thanks to using a CatBox like device that has a headphone jack, outputting really great sound that is louder than what comes from a composite or S-video cable. So hope you enjoy my Jag videos and lots more to come as I basically have a complete Jaguar game collection. Mostly thanks to a guy who sold Jaguar multicarts on ebay!
Remember to switch video quality on YouTube from 360p to 480p as it makes a big difference. Watch full screen too if you are on a PC or Mac computer. I'm sure the vids will look great on portable devices too. I have seen some Jaguar videos uploaded on Youtube in 720p and honestly I can't see a difference in quality between those and mine, even full screen. If anything mine might be a touch sharper.
So dim the lights and crank the sound and experience the true power an unmodified Jag can put out!
