Hi Pasi,

the error message you receive means that your device don't support the SET
STREAMING command. But I'm wondering because an other user reported
success with exactly the DVD model you have. Do you use the latest FW? Do
you have any other special software / hardware setup that could explain
this difference?
What Kernel do you use?
I'm still testing on 2.4.27'er kernel.

Thanks for the feedback and regards,
 Thomas
