Nextoo, you are a genius! And, your posts back in April prompted me to buy this unit. So thank you for all. It has made my life much easier, and my older Panasonic EH100 has gone on the shelf. It is painful to even use the Panasonic now that I have the XS-55.
As for streaming outside the home network, I've done everything you mentioned. XS-55 shows up on the internet. All functions are there (library, title list, setup page) except for the net monitor (via quicktime). Whenever I choose net monitor I see the quicktime logo with the pulsing line, and the word "preparing," but then it eventually says "net monitor not available."
I think it has something to do with the quicktime setting you mentioned. Is the "transport" setting to be made in the quicktime player on the remote computer, or a computer inside the home network? I assume it should be done on the quicktime player on the outside computer. Second, does the setting of "80" within the quicktime player correspond with a network setting of the XS-55 itself? I may have changed or adjusted this setting in the XS-55 in my earlier attempts to do exactly what you are addressing.
