Playing audio CD's / other media over network

I have shared my CD drive in my PC on my network and can browse to the share on the VU+ Duo box, but it won't recognise / play audio tracks (*.CDA files) from a CD (old skool I know)

But rather than rip all my CD's to MP3 is there anyway I can play the CD audio directly from the share?

Also, what about watching DVD's from there too? What's the best plugin / app?

Cheers for any advice!
