Not exactly. Part of the problem was due dbus-glib limitation, which of
course I fixed.

Other part was due to spec itself, like not providing page-browsing.
Now, it is there, but still I need to cope with the non-paging browsing.
Which fits nice for static content, but not so nice for content like
Youtube. And of course, with the ItemCount and ContainerCount.

So, you're meaning that not having a ItemCount and ContainerCount in
youtube, for instance, is a bug in the service, right? Well, I'm afraid
most of web services have that bug :)

And yes, what I'm trying to do is fixing the "problem" in rygel-grilo.
But of course, it has some limitations.
