well i've been trying to figure out how to get my sblive 5.1 to output optical digital. and unfortunatly there are no canadian dealers that i can find that sell the part i need. so perusing minidisc boards i came across someone posting this card (DP-U50 )which is available right now at a great sale price.i am wondering if anyone has any experience with this particular product? and also giving a heads up to canadians to a great deal if this is a good card. it's priced at $99 can. and on the yamaha u.s. site its at 240$?! the only problem i can see so far is that it doesn't mention xp support, i've fired off an email to them to see if indeed it isn't supported.
