I'm guessing there is no hardware-decoding of the video going on, so this is why it'll be choppy. Quicktime is a crappy player. Media Player Classic - Home Cinema (or VLC to a lesser extent) should do a better job. |

| 1268203 | 2012-04-04 00:51:00 | That may make a big difference. Some "little vid cams" record .MOV using Motion JPEG, which is basically 30fps (or whatever) of JPEG images at whatever resolution your camera records at. Decoding horsepower required isn't too great, but the sheer data bandwidth would probably be causing you the issues in that case. The camera in question is the RePlay XD. Footage is 720p at 60fps. Yep, 60. Which might explain it I suppose. |

As long as it supports h.264 acceleration it would be fine. I have a XP machine with 3GHz Pentium 4 and 2GB RAM which plays 1080p video smoothly as the AMD Radeon HD3650 offloads H.264 acceleration completely and the CPU runs at 10% What graphics card is on your XP machine? |

GeForce 9600GT. Version 296.1 |

| 1268207 | 2012-04-05 05:38:00 | GeForce 9600GT. Version 296.1 Yep 9600GT supports DXVA2 (DirectX Video Acceleration 2). You need a codec that can use DXVA2. Media Player Classic Home Cinema (http://mpc-hc.sourceforge.net/) has a built in H.264 codec that uses DXVA2 along with others such as MPEG2, VC1, etc. You do not need to install any additional codec packs. So if you use MPC_HC on your XP Machine, it should be sweet, also look at the status bar while playing video, it will show "Playing DXVA" |
