OK, guys, here are the results:
First, I tried to make tests with pre-encoded .ra files to see if it is all possible. I have installed Helix Server and I have put few ra files in "content" directory. Then I installed RealOne player on my 7650. Then I created an additional access point, to be able to connect to my PC via bluetooth, without expensive GPRS. Then I opened RealOne on my 7650 and I have tried to open URL: rtsp://myIP/test.ram mRouter started to flash, RealOne shows "connecting" and then "communicating" but after some time I get an error "connection to server timed out". I tried many ram files, in some cases RealOne gives error "not enough network bandwidth", but with the other files it connects, but then times out.
I tried many ra files encoded with G2, 8 and newest 9 codec.
I tried newest version of RealOne, but it has new menu: "default access point" and whatever access point I chose, I'm not able to make RealOne connect via bluetooth, mRouter doesn't start to flash.
So I need help What am I doing wrong? Technically it is all possible, because mRouter starts to flash, so I get connected via bluetooth. I could wach TV or at least some pre-encoded videoclips (Helix server streams files on demand), but this stupid RealOne only shows black screen and "Loading..." - then "time out".
Is there any .mpg, .avi or .mov player on 7650? Or maybe somebody will tell me how to make the new RealOne connect via bluetooth.
