Performance was also a big problem, they had a lot of issues in the beginning justifying the amount of time it took to encode and especially decode the images.

Performance was also a big problem, they had a lot of issues in the beginning justifying the amount of time it took to encode and especially decode the images. IIRC it was of the 100x the time of JPEG and that meant that at speeds of the time the bandwidth saved was overshadowed by the decode time. I did a lot of working with it and had quite a lot of problems with performance of the sample software.
