simply put. use the .mov container/extension, with the H.264 codec. also depends on what resolution your video is in. read below
Standard Definition, 720x576, >1500kbps, H.264, progressive scanning
High Definition, 1280x720, >6000kbps, H.264, progressive scanning
High Definition, 1920x1080, >9000kbps, H.264, progressive scanning
Note that the SD is in 4:3 while HD is in 16:9 aspect ratios. If you want 16:9 SD, go 1024x576 for the resolution.
personally I wouldn't use wmv codec, terrible compression quality. of course if you're worried the machine is not able to read mov, just download a copy of vlc and bring along just in case.
