Anyone know anything about mythtv?

I have it up and running, but I can't view channels/scan for them etc (it scans and says no signal).

I know the TV card is working as I tested it in windows (am able to get SABC1,2,3 and etv).

Ideas?

Addtional Info:
Code:
04:01.0 Multimedia controller: Philips Semiconductors SAA7131/SAA7133/SAA7135 Video Broadcast Decoder (rev d0)

Is that the mustek one?

what implementation of mythtv you using - I've started playing around with mythbuntu - looks pretty neat.

Nope its an LG LTT-200 (cost me like R200) haha/

I am running Ubuntu 8.10, with mythtv installed on top of that.;)

It looks really cool, I just can't get it to pick any signal up.

You need to setup the backend properly to get channels working, make sure you have pal I and southafrica as your frequency table. But to be sure your tuner card works with linux first, use mplayer or VLC to test it.

Not sure what you see, but you want to make sure that its PAL (specifically PAL-I I think), along with selecting the southafrican channels. I also found that my aerial made a *huge* difference...

g'luck and let us know if you come right

I have set it up for PAL - will try PAL-N and I've tried the SA channels as well as "try-all".

How do I test my tv-tuner with VLC?

I realize now that this will only work on ivtv supported cards but this is how you do it:

Install ivtv-util (search repository/package manager and install)

Then in terminal launch:
Code:
vlc pvr:// :pvr-device="/dev/video0" :pvr-norm=0 :pvr-frequency=-1 :pvr-bitrate=-1
In terminal tune to a channel with command:
Code:
ivtv-tune -f 0000
(replace 0000 with a frequency)

My frequencies are...
SABC1
183.75

SABC2
207.25

SABC3
799.31

etv
767.31

Thanks, but I am encountering errors:

Output from VLC
Code:
File reading failed:
VLC could not open the file ":pvr-device=/dev/video0".
Your input can't be opened:
VLC is unable to open the MRL ':pvr-device=/dev/video0'. Check the log for details.
File reading failed:
VLC could not open the file ":pvr-frequency=-1".
Your input can't be opened:
VLC is unable to open the MRL ':pvr-frequency=-1'. Check the log for details.
File reading failed:
VLC could not open the file ":pvr-bitrate=-1".

VLC is unable to open the MRL ':pvr-bitrate=-1'. Check the log for details.
Is the tv-tuner normally located at:
Code:
/dev/video0
?

I have tried tvtime but I can figure out how to search for freq/change channels etc.

Thanks for the suggestions so far guys!

Depends on your device, you might have to change it but I'm not sure how you figure that out, I have a haupauge so it worked out the box without needing to probe.

Edit:
Just open VLC normally, then go:
media> open capture device> select 'PVR' but test other capture modes (under 'advanced' tell me what device name you have) and press play, I can view TV this way without using terminal to launch VLC. I only need terminal to switch channels.

BTW try the retro theme for mythtv that's my fav.
