not releasing this fix reflects badly upon the SonicBlue brand.

And the fact that SBLU ran out of cash and went bankrupt doesn't?

Realistically, Sonicblue doesn't exist any more. I don't know the terms of D&M's purchase of Rio, but it's possible that support for discontinued products (effectively a liability) wasn't included.

Having said that, the Rio Central is still listed in the support section of http://www.rioaudio.com/

So, get on the horn to Rio support and harrass them.

But don't bother worrying about Sonicblue's brand image. Sonicblue doesn't exist any more.
