had a play with msi afterburner and whilst the video quality is good the files are huge
30 seconds of gameplay came in at over a gig, not ideal if we plan on doing 15-20 minute videos
and that was recording at 720p any suggestions?
lol thats small

mine in fraps are close to 5 gig per minute

if you serious about recording get more hds and dont record the game from the same drive you using whatever to record with.
surfer if you want quality you have to have some trade off . fraps and dxtory are best. set them up right though and you wont have many issues.
