DVD-A catalog?

Is there an online list of all the DVD-A available on the market? Amazon has an extensive list of CDs but their DVD-A list leaves something to be desired, I have 3 titles that they don't have listed!
In Canada, HMV/Amazon.ca has a list of 503 DVD-A titles on their www site. You'll likely never see a list of ALL the titles available on the market. There will always be small operations below the radar screen.
