Hi. I was just wondering whether anyone was currently using a DVB card with Freevo. I've just installed a new Avervmedia DVB-T card in my freevo Box (It's a budget kind with no MPEG2-decoder) and have the latest cvs of mplayer playing tv from it with no problems (eg with the command mplayer -vo mga dvb://"TEN Digital", where "TEN Digital" is the channel name).
I don't have a DVB card but may be able to help...
Has there been any work done on modifying the channel code to deal with named channels rather than numeric ones ? I imagine some kind of translation table would be the easiest way to go. This would also have to be implemented in the record_daemon module aswell I imagine.
As far as I know channels are already treated as strings and not numeric. I am working on centralizing channel changing code to allow more controll over your Freevo channel list and what devices to use for each.
I also want to record from my external Sattellite box via the (net yet operational, but should work eventually using vfl2/bttv) composite video in. Has any body got using an external channel changing command rather than bttv/mplayer/VFL channel changing to work ?
Yes! :)
What kind of sattelite box do you have? I made some freevo code to send IR command to my echostar branded receiver and plan on adding another module for 'normal' sat and cable boxes (but hooking in lirc's irsend command should do until then).
Also, are you talking about the composite video connection on your DVB card or another v4l device? Does the DVB only ancode to mpeg2 on the tuner input?
For more info on my plans for some of this stuff see:

Anyone toyed with the idea of writing the DVB mpeg 2 streams straight to disk. I could probably implement this using -vop copy easiliy enough.
This might be pretty easy. Can you tell me how the DVB device works? Can you simply read a stream from the device and save it to a file? The ivtv drivers (for Hauppage pvr-250/350) work like this. For those drivers I cooked up some python to record natively in Freevo. I wrapped up some device ioctl calls in module functions and on the recording side just call some of those functions to set up the device then read from it and save the data to another file. I think that if the DVB cards / drivers work similarly then the same could be done for them. If you want to look at the ivtv code see src/tv/ivtv.py and src/tv/plugins/ivtv_record.py.
