Nothing strange in my names, just alphanumerics and underscores. I would rename something like GigliDirectorsCut_Disc1 to GigleDirectorsCut_Disc1SEE. Names are purely made up for this example of course....
However, this part seems to possibly be better now, although I haven't verified it's 100% yet. I reset to defaults, reconfigured, again refreshed upnp, and waited a couple of hours, and some of the files I knew to be missing are back. Also, speeds are better, but still not fully right. Computer read speeds are now what I'd expect (~50Mb+ on wired 100Mb network and ~15Mb on wireless g), but PS3 speeds are still horrible. Slightly better than before at 2-3Mb vs 1-2Mb, but unusable. Have tried wired and wireless on 2 ps3's (original and a slim). Speeds are similar whether I'm trying to stream files or just copy.
