Thanks for the reply, but could you answer a couple other things? I'm not familiar with the Xing Technology encoder, so can you tell me what kind of compression ratios you're getting? Are there options to trade off encoding time for higher compression? If so, do you have a feeling about what the upper end for this compression and time scale is? Thanks again. Bill Alves
