With the previous version I tried I thought it was just that my 1.8 G5 isn't fast or powerful enough for this program, but I see other people with very fast machines are also experiencing the jerkiness. I want something that can do what Photo to Movie does, using large files (I want to be able to watch them on an 8-ft screen as well as my TV) and burning to DVD without crunching them so badly they are unviewable even on a small screen. I tried FotoMagico, which I liked very much, but the only way a decent slide show could be created needed the use of a Macintosh. Only one other member of my family has one.
