I have finally found the optimal solution, and still being able to use the Elgato Video Capture i bought (see previous entry about Playing & recording 8-bit and 16-bit consoles on you Mac / computer). While the Elgato / DVD recorder combination worked excellently with all my PAL systems I still couldn’t get it to work with my NTSC NES and my japanese Famicom, since the DVD recorder was PAL region it messed up the images.
I had to buy rca y cable splitters since the Famicom only had one output of composite image and video cords, now being able to split the signal to two places I can play through connecting the Famicom to a TV while also having it connected to the Elgato, which actually captures the video and image perfectly however generates a black image (“no signal”) while recording. The rya y cable splitters might not be necessary for the regular NES since that console already has two outputs, one for the antenna input in a PAL television and also the composite on the side, however it is more nimble not having to search for the channel and just playing through the AV channel ^_^
If anyone has any questions about this topic feel free to ask me, I’ve been researching into it and going through a lot of trial/error phases to know a thing or two about it by now ;D
