- 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.
