DVB-T in TinyCore 3.7.1?

[AlejandroPadrino]

Can anyone play TV with TinyCore 3.7.1?  I want to play with VLC or MPlayer.  Don't found dvb-apps for TinyCore.  My receiver is Hauppauge WinTV-900, firmware xc3028-v27.fw downloaded.

Thank you.

Haha, I've just tested that only a few days long ago: For me (using a Hauppauge Nova-T USB DVB-T receiver which also requires a firmware file) the absolute minimum steps on a "plain" TC system (i.e. booted from CD-ROM without any extensions installed) appear to be:
    tce-load -wi firmware v4l-dvb-$(uname -r) vlc ; alsactl init
If you don't have a 'channels.conf' but know at least the frequency of your TV transmitter (e.g. 690 MHz) you could use vlc dvb://frequency=690000000 as a simple test if all your hardware is playing together nicely.

I'm not suggesting that this is the absolute minimum, nor am I considering this to be any good for ongoing viewing pleasure (e.g. it only defaults to one of the channels that is in the transport stream), but it is at least a start.

Hello maro, I was follow some things founded at  http://forum.tinycorelinux.net/index.php?topic=751.0  but can't show TV.  My logs are next ...

[0x9178854] main stream error: cannot pre fill buffer

Note that d-bus service was activated manually from services panel.

I load TinyCore directly from .Iso image file with Grub4Dos.  All extensions in ondemand mode.

That is a bit tricky to tell from here, but a few minor observations:
(1) Turning 'dbus' on or off doesn't make any difference for me, I'm also getting to see the same set of error or warning messages, BUT the last one (i.e. [0x9178854] main stream error: cannot pre fill buffer). Nevertheless I can still watch TV.
(2) What I've noticed when comparing your set of messages against mine are subtle differences in upper/lower case and the fact that here it shows 'VLC media player 1.1.9 The Luggage (revision exported)' as greeting. Therefore I wonder whether the extensions are the same (BTW, im using: 189dd82fd9fed038b83fab51e96cfc1c  vlc.tcz)
(3) Comparing your list of extensions against mine shows that you have quite a few more, so to get to a "baseline" I'd suggest you boot with 'base norestore' and only load your specific firmware and the two extension (plus their dependecies) that I are required (e.g. via tce-load -wi v4l-dvb-$(uname -r) vlc, plus enabling the sound card if that is needed). But do this only AFTER you've updated ALL involved extensions to the latest version from the repository.
