That was the problem I had with mine, recording game footage. I haven't watched TV in years. There was a massive delay between what was shown on the screen and what was really happening, enough to the point that it actually screwed my game up.

Make sure to try a complex battle that would require good timing, just try playing, you don't need to record. If you do fine in the battle, great, maybe they finally fixed the delay issues. If not, then you'll have to either adjust to that or try a different one.
