What can cause poor quality video in Canon point&shoot camera?
Are you dragging the videos and watching them in an editing program such as Final Cut or Premiere Pro? If so, it is probably because you need to log and capture and run them through 'Compressor' to convert the files to a suitable format (say ProRes(LT)..)... I am guessing you are just viewing them in a default viewer, which in that case, as mentioned above it may be due to expectation from watching them on a smaller, lower resolution lcd screen on the camera..Though, the camera you mentioned should output fairly decent video... Hope this helps.
