Using ADVC-50 and capturing to DV Type 2, audio 48 khz.

The DV/avi file sounds and looks
great. but.....

When I TMPGENC to mpeg1(vcd), the
audio sounds horrid.
I know conversions from 48k to 44k
can produce some aliasing, but this
is unacceptable.
No change in using the de-emphasis
flag.

Anyone else?
Any solutions?
thoughts?

thanks.
