I guess I know why you want OGG support... My suggestion for now would be, just continue to develop using .wav and buy DGS and then get something like STYX or find a free variant here on the forum... And then convert the code... Ensure you use modular coding practices...
So yeah... I think you should get your application closer to completion and then work around the sound issue when you have the budget or find another solution... Nothing beats royalty free
(Of course unless you made it lol)
Let me know if I can be of any furher help...
Also Brendy boy was saying... Type Load DLL into DBPro and then press F1 while the cursor is within it... If confused just highlight the code and press F1
It should turn blue first... Then press F1...
