We are putting together an e-sports team at college and among the games we play. There's Project M on the Wii and Melee on the GameCube, so we need a CVBS/RCA video capture card to record and upload our gameplay.
So far we have tried with an Encore and a GreenLeaf video capture card without any success. We were unable to find any decent USB/PCI/PCIe capture cards that support this kind of input. What is a good hardware choice for this? It must be compatible with Linux.
