That's not a standard setup. Too much can go wrong.
Try it like it's meant to be setup with a router. There was no need to use a CROSS OVER cable. A normal cable will do fine. I've lost count of how many times folk make their own cables. Are you doing that?
I keep loosing the connection between my computer and my TV.
They are connected by a ethernet wire cross-over.
I tried connecting the computer directly to the TV and by wireless router (TV to router by ethernet wire cross-over, then router to my computer by ethernet normal wire.)
Everything I tried give me the same result, I watch a movie and then I got the message on my TV that it's deconnected.
I have Windows 7 home premium 64 bits and Share PC manager 4.2.
I tried reinstalling Share pc manager, same result.
Anyone has a solution?
