Good DVD changers to use as transports?

This weekend a knowledgeable friend helped me go through my audio system to diagnose the source of a rather annoying problem that makes it difficult to listen to music for very long. I have added a power conditioner, better interconnects, and other tweaks, but it appears that the problem is the CD changer that I have been using as a transport. My friend has recommended that I get a different transport. Because I prefer a changer as a transport due to a health problem, it appears that my best option is to go with a good DVD changer. My DAC is a modded Art Di/O, so the DVD changer must have a coax out.

I know nothing about what is recommended for DVD changers and would appreciate any recommendations from fellow Audiogoners. Thanks for any help.
