He's right; trust him. The 44.1 / 48 parameter is one where "just 
picking the higher number because it must be better" does not follow 
through with the expected results. SRC (Sample Rate Conversion), done 
properly is a processor intensive task that FEW people are willing to 
wait for when there are more streamlined (READ: lower quality) 
algorithms to choose from. QuickTime SRC used to be NOTORIOUSLY bad. 
Dunno about it now, I only do SRC on a a ProTools workstation or with 
BarbaBatch software.
