Actually, you are right, one can insert data in the decoder. Appearantly you can't insert TS data into the encoder, but that is not what you asked. Since vdr is using this feature, it must be possible using the standard v4l-dvb drivers. VDR however does not interface in the same way with the hardware/drivers as mythtv. I found that when I used a certain type of CAM, which worked in vdr but not in mythtv. What you are looking for is an option in myhtv such as in the "settings-playback-pvr350 hardware decoder settings" : use the pvr350's TVout/MPEG decoder, but then for the nexus-s. I dont think IVTV is intended to work with DVB devices. It original intention was probably the support of pvr150 type analogue tv cards under linux. The dvb drivers existed already years for the nexus-s. I know it does not help, but I think the place to ask is on the mythtv list. http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
