Scroll handles a wide range of video formats but some video format containers can vary considerably, AVI being one of them - a lot depends on compression and just exactly which codec was used to convert the video in the first place. Storage Options are aware that some types of videos simply will not play on the Scroll if they don't meet the hardware standard of the Scroll itself. What this means is that the hardware on the Scroll is hardwired to handle the higher quality types of video files.The Scroll cannot adapt to using low quality files satisfactorily.
A high quality AVI type video could be over 1Gb where-as the same video reprocessed and more highly compressed could still be the same film and still be an AVI but could be compressed to a much smaller size -for example 650Mb but not play on the Scroll.
When converting films for the Scroll it is best to use constant rates for the video and audio compression as using varaible rates (which make smaller files) can cause bad misalignment of video and sound making them badly out of sync. This is not an easy subject to understand without some learning about how video's are created using the many different formats: i.e. Lossless formats which should play OK or Lossy formats which make smaller files but are less likely to play satisfactorily.
Storage Options has a good tutorial on this subject which you can find here:
