Phase one is complete. I have the above card up and running showing pictures through both xine and gxine on a (Edit: LiveCD) of 4.1.2.

I would like to go to the next phase and actually save the stream to the hard drive using dvbstream 0.6. The closest to success was video but no audio - yes the audio PID was correct.

I have tried various input to dvbstream including this excerpt from a slightly longer script:

dvbstream -bw 7 -f 718500 -v 512 -a 650 -ps -o > $path/$name-$timestamp.mpeg &

Which "should" save the ABC1 stream to the file defined as $name-$timestamp.mpeg to the location defined in $path.

I have tried using the "full Monty" with QAM, FEC, etc defined but I get the message of the sort - cannot find the frequency. I have it running in the background as I type this!!

The correct input command seems to elude me.

Any suggestions very warmly welcomed.

Edit: Using Gtb-DVB, the readme.txt confused me by the last two lines regarding saving.

Start gxine like this:
gxine dvb://DasErste#save:1.wmv

Edit2: A search for DasErste showed it was a TV station, so sharp as a tack, I simply entered:

gxine dvb://ABC1#save:Test.mpeg # There is a . between Test and mpeg!

and it saved.

Now all I need is a script that will set the duration of the save. I have some ideas.

Phase three: What do I need to do so that I can use one of the tuners to save a stream and use the other tuner to view another stream?

For what it's worth, I think if you're running from a CD, with a Save file on a hard disk, the hard disk (and save file) are mounted by Puppy when it boots and remain mounted for the whole session. I could be wrong; for years I've only run Puppy from a multisession DVD without a hard disk at all.

Thinking about it overnight could I simply call shutdown from inside my script?

NO!! NO!! It simply freezes everything. So what is the "clean" way of shutting down?

Re "Phase three: What do I need to do so that I can use one of the tuners to save a stream and use the other tuner to view/save another stream?"

The answer was right there except I couldn't see it. Referring to

http://linuxtv.org/wiki/index.php/Zap

gives the answers - well most of them!

The method I have tried with success is:

1. In one terminal run

tzap -r -c /your_path/channels.conf "your_channel" # from the channels.conf file

2. In a second terminal run

cp /dev/dvb/adapter0/dvr0 /your_path/your_channel.mpg

Repeat the above two steps (3rd and 4th terminals) to save another channel. Clunky - yes. Works - yes.

I thought I had kicked a goal when I saw this on the above site

usage:
tzap [options] <channel_name> zap to channel channel_name (case insensitive)
-a number : use given adapter (default 0)
-f number : use given frontend (default 0)
-d number : use given demux (default 0)
-c file : read channels list from 'file'
-x : exit after tuning
-r : set up /dev/dvb/adapterX/dvr0 for TS recording
-s : only print summary
-S : run silently (no output)
-F : set up frontend only, don't touch demux
-t number : timeout (seconds)
-o file : output filename (use -o - for stdout)
-h -? : display this help and exit

Unfortunately the tzap file that I am using does not have the -t option (r -x, -s, -S, -F, -o (would be sooo handy!) or -h for that matter) so I cannot do timed saves. Sigh!

hi Mercedes350se

it might be worth a look at the timer script i used in the getiplayer.pet.

Thank you for the suggestion.

I have found a pet for "at" which I have installed. There is a lot going on at the moment so I haven't tried it yet - mainly because an early part of my script is not working - so it is still a work in progress.
