iTunes suit commands not working for remote machine

Question

Hi all,

I have found that Standard Suite commands in iTunes are working for remote machine but not the iTune Suite commands!

ie. if I am using this command, it is working fine:

set targetMachine to "eppc://[email protected]"
tell application "iTunes" of machine targetMachine
    quit
end tell

but if I am using this, it is not working:

set targetMachine to "eppc://[email protected]"
tell application "iTunes" of machine targetMachine
    previous track
end tell

Although it is working for local machine!

Can anyone suggest me, if I am wrong somewhere?? or my conclusion is right???

Thanks,
