@manu I had a similar experience when I saw an aged forum post fro the author of _The Windows Bible_ who, along with me, could not figure out why OverDrive wasn't working with streaming video on our 64-bit systems.
The obscure answer was revealed to be a conflict with our sound cards, an answer no help team at my library nor Overdrive would research or suggest.
Worst feeling: that 2003 post is followed by a single 2004 post by the original poster, saying: "Never mind, I solved it".
With no explanations or details of any kind.
@ParadeGrotesque I solved my problem, by discoveribg that the documentation was lying... Sigh
