Rip audio to WAV in 24-bit?

Hello:

I use dvd::rip exclusively for audio.  I notice the resulting WAV
files are 16-bit.  This implies some resampling is done since audio
off a video DVD is 24-bit.

Given that dvd::rip is going out of its way to downsample, is there
any way to prevent it from doing this and get it to output 24-bit, 48
kHz WAV files?  There's no options in the GUI for this that I can see.
 Perhaps if I dug into the code - is there a relevant section or
statement that I should comment out?

Thank you,

Mark Lanctot
