Good luck.

ioctl call should I use to know if the fronted is currently active?
Anybody has an opinion about that?
I know, I cant spell frontend properly :-),
but other than that, what would be the correct behavior when opening the
frontend in readonly?

Hi,
I'd like to understand the behavior and meaning of the LOCK returned by the
fronted.
If I open the fronted in readonly, and ask for the INFO, it is possible that I
get a LOCK but no
data is actually received.
This because the fronted receives data ONLY while it is opened in READ/WRITE.

Is it true?
I would like to receive the whole TS of whatever is currently tuned. (possibly
in read only).

Hi,
I've understood a bit more how demux, dvr and rigbuffers work, but I still have
a couple of issues.
I've been studying tzap, which seems much easier than gnutv.
tzap opens the demux twice (audio and video) and then opens the dvr to read the
multiplexed data.
There are 3 ringbuffers
Hi,
I've tried to add an extra argument to gnutv to set the size of the
dvb_ringbuffer via

I have not really understood the difference between dvr and demux.
It seems that gnutv uses the dvr to read from the DVB card and then copies the
content to a file.

I usually save TV to a network disk using gnutv.
Sometimes I get

The network is wireless, I'm using 54 Mb/s which should be more that enough for
at least 1 channel.
Sometimes though, under heavy load it stops.
I think some network congestion makes gnutv read too

But again, does anybody know a tool for that?
