In the bootsequence of QNX 6.3 is this comment:

unable to start “io media” : no such file or directorie
mount : can’t mount / (type “io media” )
mount : possible reason : no such devices or address
starting extra run commands

The cause for this: Haupauge Wintv

Where I can find the command “IO-Media”?

Not sure about the location of io-media, but unfortunatly I tihnk it’s fair to assume that WinTV is not supported under QNX, not without a fair amount of expense, anyway.
