Good news Ivan...<br>
<br>
I upgraded the client on the Mac to .19. When I started it up, it
required me to also upgrade the backend (0.19 is now available, but
masked on Gentoo) before it would run. So I upgraded the backend,
and the Mac frontend works great now.<br>
<br>
Even better - the upgraded protocol seems very smart - I can even watch livetv or prerecorded shows on my wireless laptop!<br>
<br>
Very happy. Thanks for your help!<br>
