I've played with these Sony cameras a few times -- as I recall they can
be sluggish to respond to commands, and maybe that's what you are seeing
here.  Nevertheless, I'd like to fix libdc1394 so that we cope with it.

Why are you commenting out the dc1394_video_set_mode() command?
Wouldn't that make the value of selected_mode mostly irrelevant?

Could you run your program as:

DC1394_DEBUG=1 ./grab_new2

and post the failed output to the list.  Hopefully some additional
useful details will be revealed.

Thanks,
