Looks good so far....

Each plugin has a priority value. The priority of the aRts audio sink is 
higher than that of the OSS sink, i.e. piave tries aRts first. If the 
connection to the aRts daemon fails, piave will try the next plugin, i.e. 
OSS. I have had no problems even though kdenlive is starting piave inside 
artsdsp, but I think it would be nice if the "renderer"-configuration, would 
not read "/usr/local/bin/piave" but "artsdsp /usr/local/bin/piave -d". That 
way I could add a couple of more switches and take out artsdsp if I wanted 
to. But this is not very important since I find it pretty convenient to 
start/debug piave in a seperate shell.

Interesting, so it works? Keep in mind, that piave is not using the seperate 
audiotrack, but the audio which is interleaved inside the DV video stream, so 
in case you did some audio editing in Adobe, piave will probably miss it.

Oooopsy.. ;-)   Can you tell me what exactly you are doing?

I think it would be much better if one could just dum the output to a file, I 
find the small list pretty unreadable. I don't use it anyway, I just start 
piave in a seperate shell. 

I have a couple of oother small things which I'll post as soon as I find the 
paper where I noted them down...
