i asked a question similar to this on ACC
this is what they told me
<big><big>click on spoiler</big></big>
<div class='spoiler_toggle'>Spoiler: click to toggle</div><div class="spoiler" style="display:none;">#1 well I have a recorder(doesnt come with wii) but there is no way to record a video without some sort of recorder or you can use a video camara but that sometimes has bad qulaty. other than that you can only take pics on the wii it's self
#2 I use a DVD recorder, they're usually about $40-$100. There are also other methods such as capture cards to record gameplay, and TV Tuners, though I wouldn't suggest using a normal video camera, as they have terrible quality.
#3 I heard people use DVRs
#4 I bought my GameBridge from Amazon.com for about $10...
Just plug your Wii into the GameBridge and then connect THAT into the CPU...
But, I think the price has been raised since when I bought mine...
#5 Capture cards, dvd recorders etc.
# 6I use a DVD Recorder. Was $80, but the quality is really good.
