So, this tutorial has a review of recording devices, including ones that support HD recording. It does note the following
I WILL BE LISTING SOME HD COMPATIBLE RECORDING DEVICES that enable you to record in standard and play in High Def simultaneously later in this article. However the prices can vary dramatically on these devices. There is only one somewhat affordable external device that allows true HD capture and that is the Hauppauge HD PVR and it is listed below.
It also says
As far as I know there are no affordable external devices that record 1080p or from an HDMI cable. The Hauppauge will do HD but it will only record in 720p or 1080i.
Mind you, this guide was posted 3 years ago so there is no guarantee that the devices haven't improved since then, but this seems to be a very complete guide.
Honestly, I think you're going to find better support on the GameDev side of things. A lot of players record their videos (especially those in MLG) but a lot of the times they won't care about audio syncing, or perfect framerates. You can take a look at this guide over at the MLG forums, but a lot of their focus is on cheap rather than quality.
Wii Classic
The original Wii supports GameCube games on disc, and has GameCube controller ports hidden under a plastic door.
Wii Family Edition
There is an "updated" Wii that goes by "Wii Family Edition" on the retail box. It is identical in many ways to the old style Wii, down to the form factor. However, it does not support GameCube discs or controllers.
The best way to tell them apart is the model number - the Family Edition is model number RVL-101, and the "classic" Wii is model number RVL-001. This number is printed on a label on the bottom of the unit when it is in the vertical orientation. If it's lying horizontally, this label is on the right side of the unit when looking at the front.
You can confirm this information on Nintendo's support website. Click to view the Wii manuals, and you'll see two sets, one for the RVL-001, and one for the RVL-101. The 001 manual mentions the GameCube ports, while the 101 does not.
In addition to the model number change, there are a couple of other telltale signs:
- The plastic panel covering the GameCube ports on the Family Edition is screwed down, where on the older model it flipped open. Underneath, the holes are present for the controller ports, but the ports themselves are empty.
- The serial numbers on the "classic" Wii tend to start with L, and the Family Edition serial numbers appear to start with K. However, since serial numbers are at the discretion of the manufacturer, I'd hesitate to act on that information alone.
- The Family Edition Wii doesn't ship with the vertical stand, although since the case design is identical to the previous design it can be used horizontally or vertically.
- The Family Editon's Wii logo is parallel to the disc drive slot, (making it correctly oriented when the unit is horizontal) whereas it was perpendicular to the drive slot on the original Wii.
Wii Mini/Wii U
Since introducing the Family edition, Nintendo has also released the Wii Mini in some markets, which does not support GameCube games at all. It is also missing network support, and has a top-loading disc drive rather than the front-loading drive of the original Wii design. It is essentially a bare-bones, stripped down version of the original Wii.
The new iteration of Nintendo gaming hardware is called the Wii U. Despite similar names, and cross-compatibility with certain Wii peripherals, the new Wii U does not support GameCube discs either.
Best Answer
You need a capture card. Most capture cards are pci but there are a few out there that work with usb. You also need software to perform the capture which may or may not be bundled with the card.
