If I understand you correctly-  then if my QuickTime movie plays back with a
data rate of 37.5 kBytes/sec - then is actually the data rate of 300 kBits
/sec ?

Also - what is the ideal Kbits for your average DSL speeds ( basic Internet
standards) 

DSL-Low - 100kbits?
DSL-Med - 200kbits?
DSL-Hi - 300kbits? 
56k modem - kbits ?

Also - I noticed that when you use a QuickTime pro export - Hi quality -  it
uses the data rate of 82.029 kBytes/sec -  so is that actually 656.232
kBits/sec? - Very high ( by average Internet DSL standards)
