    I'm just wondering. From the size of the file, it sounds like a QuickTime 7 HD movie clip, maybe??

    If it is, your G4 processor is going to find it a bit of a struggle to decode. :(

    If you had QuickTime Pro you might have better luck by converting it to "Apple intermediate Codec" of AIC.

    On the plus side AIC requires less processing power. On the down side it makes the file mushroom in size . This may become a problem if the hard drive cannot deliver the data quickly enough for you G4 chip to process.

    There is a solution to that though……. Get a Macbook! :D

    well there seems to be a drop in the quality yes.. the resolution is lower, and the gamma looks different. what did you use to convert it, and what is the name of the extention file?

    DV is near broadcast tv qaulity (ntsc/pal/secam) by the way.
