It really depends on the OS and API used to decode the video.  Quicktime has
similar performance using either Motion or Photo JPEG, and ffmpeg treats
them equally well in Windows using FFDShow.  I don't know if libquicktime is
handling these codecs on Linux or not.

Use Photo-JPEG for non-interlaced sources and Motion for interlaced.  Or
deinterlace before converting to Photo.
