i was doing a search about this model but all i could find was a mention to the previous model working with v4l so no idea if it will work properly but possibly(hopefully) it will
i have a very cheap tv card, it works very well in linux including the video in connector, the sound foes to line in on the sound card
all you need is a app that captures the image, i never done this on linux so no idea which one can do it but afik there is many that can do it
all you need to do is know the port and set the app to capture from that port
remember that no matter the quality of cables or tv card/capture card, the original quality of vhs is usually crap, at best at 512x384 but very compressed and many colors very weird wit lots of noise
after you capture the video you will need to edit the video to crop, remove possible damaged borders and correct brightness, contrast, colors and other nice tricks that avidemux can offer between other apps
