Just wondering if anyone knows the differences between the three different coloured singles of the rescue my video tapes and If so are they all equally good quality or are some better than others in respect to the chip used in the converter?

I see that there is a

Red one

White one

Black one

It looks as though they are all the same thing and possibly based on the easy cap device usb model that is sold seemly everywhere from Amazon to ebay at prices from next to nothing to a fair more. I am thinking that the magix dongles be it whatever the colour is a better quality item in anycase but was just wondering.
