You will need to re-encode the video to H.264 or some other more compressed form of your choice after capturing. Note that the file size will be very large, about 30GB per hour. If that doesn't work you also need to use different software which will allow using a fast lossless codec for capture, like Lagarith (LAGS) in YUY2 mode. You should try using a second hard drive, not the boot drive, for capture. Is it the capture device and software for the device? When a capture device relies on software to encode, dropped frames are the result of either a CPU which isn't powerful enough to keep up or a hard drive that can't keep up. Because everytime i play my 360 i always get 20 frames or less and not a solid 30 frames.
