Again, thanks for responding.
No the PS3 has not been turned on the whole time, I've tried multiple restarts of both PS3, laptop and router.
It seems jamcast uses about 22,000 kB of memory.
I've tried uninstalling VidZone, but no luck there either.
Restarting the service jamcast does the same trick as un/installing it, ie; the icon shows up on my PS3 but when accessing it, it gives me that DLNA error again.
It also seems like the device tab in Jamcast manager repopulates really slow, after restarting the service, the jamcast icon will pop up immediatly on my PS, but in the jamcast manager on the laptop it takes like ~5 minutes before my PS shows up.
I currently live in an apartment building and my PS shows 6 different WMP-icons in addition to mine.
On the devices section in the JSM it is the same thing, except there is only a few that is identified as WMP, the rest is just called "default upnp device". But I figure it's the same ones as shows up on my PS because it's the same number of devices.
Maby all this could be making some issues?
I wonder if changing the channel on my wireless could be helpful?
So far I have not bothered to do so, because I've never done it before, and since it worked once I really thought the solution had to be simple, but..
Do you think it could help?
Other than those unidentifiable default units, the only things showing is my PS3 and my router.
Another thing that is maby worth mentioning is that when I try to make changes to any of the settings of the devices listed, the JSM ALWAYS locks up, and have to be restarted for the changes to seemingly take effect.
I'm quite baffled with all the issues I've had with this, especially since I'm using a laptop that I'm certain has NO malware or other stuff, and is just over a month old
Thanks for your help so far!
