after a lot of work...and many days, i finally got to write a .tpl file correctly..the format is the following.
The frequencies are in Mhz and not in Khz....
so for example here in athens Greece we have 3 transponders one on 690000 khz, another on 682000 khz and another on 674000 Khz
so the first field is the frequency (in MHz) the second field is polarity..(that is used for DVB-S satellite - it should not be used for DVB-T) so use H. the 3d field is the bandwidth..
make a txt file write the transponders and rename to tpl..
I got the winamp plugin to work with the terratec cinergy Tstick BUT the plugin can only show MPEG2 channels..it will not show MPEG4 (h264) channels.. i tried everything..
so i ditched the winamp plugin and went directly to VLC.. VLC is capable of showing DVB-T, DVB-C and DVB-S channels..and actually plays everything, you can create playlists of the scanned channels.. you can get it embeded in RR and sendkeys to it..it is very easy.. i got it working good aswell
i also tried DVBviewer which also works nicely and plays everything you can create playlists of the scanned channels here aswell..this is my prefered software..it is more flexible than the above 2...i got it embeded and i am sending keys to change channels and it works quiet nicely..
So i believe development should be in creating a VLC plugin.. the RR team has allready made a video plugin for VLC, so making that to work outside "video.skin" and be able to play vlc playlists is not that hard i believe..but it is waaay over my head..
Lambospirit has a plugin for VLC (which he wrote before native VLC rr support) but i asked him if he can refresh it to make it work with latest VLC..we will see
1 more thing i was driving with my car on 100km/hr and was having 90% signal with the cinergy stick and DVBviewer and the supplied antenna yesterday..(the antenna is a magnet small one and was outside of the car) at least in open areas, when i was between buildings the signal was lost
good luck and tell me if u need any help
