Thanks Peter. That explains the reason for the 0000 for the signal snr etc. am i doing something wrong to capture the stream or even play it? is there an programme that will tell me information on the stream tzap has connected with? so i can make sure i am actually receiving a valid mpeg stream . any ideas so i can pin down the problem would be greatly appreciated.

The driver doesn't report values for signal strength/noise ratio/etc. Only whether the tuner has locked into a channel or not. It's a bit misleading that tzap always prints zero here for the other stuff even though the kernel reports that the driver doesn't support these infos. > if i try and capture stream using the > following: > > cat /dev/dvb/adapter0/dvr0 > myvideo.mpg > > i get a file of zero bytes. if i try and use mplayer or xine they both > fail too. since this is a stb also i can play a scart cable into it and > i do see that the channels are being changed when i tzap but i just > dont seem to be getting any data back from the stb. > > does anyone have any ideas? hm not really. just to be sure, tzap has to be running(e.g. in another terminal) while you are trying to capture data from /dev/dvb/adapter0/dvr0. (btw. iirc tzap can also directly dump the data into a file by itself) xine never really worked with this driver for me(for unknown reasons).
