Setting up MythTV with Kworld’s PVR-TV 7134SE

Posted in Uncategorized by sqllyw on 08/09/2009

My personal experience in the setting up of mythtv, tested PCI Card
KWorld Plus TV Analog Lite PCI(PVR 7134E) and ITO23 REV:4E(a 7135 based card)

Got a need lately to view TV from a laptop computer and decided to set up Mythtv for that, it took a while to be able to do this, the main problem is the TV tuner card, the tip I can give is, find a card fully supported by Mythtv before starting, this will save a lot of time. anyway, I finally got my box up and running almost 99%, still have 1% that I’ll figure out later, steps to setup:

0) hardware part, I use a simple approach, connect the video out and audio out of my set top box to the video in and audio in of the tuner card, this make it the composite input(the card has RF and S-Video inputs, but I’m not using it), for the audio, since my set top box uses RCA, so I have to use a RCA to mini 3.5 jack adaptor. optionally you can connect from the audio out of tv tuner to the line in port of your pc’s sound card, this is not really necessary if you want to use only mythtv for TV viewing.

1) install first Ubuntu 9.04 desktop

2) sudo apt-get update

3) dmesg | grep saa
you should see your card there, but type of card is set to UNKNOWN or GENERIC(can’t remember exactly), if you find the card there, proceed to #4 otherwise Google:)

4) sudo pico /etc/modprobe.d/alsa-base.conf
look for the line: install saa7134 /sbin/modprobe –ignore -install saa7134 $CMDLINE_OPTS{….}
change the $CMDLINE_OPTS to card=59 tuner=56, save and reboot

5) dmesg |grep Kworld

[ 12.104209] saa7134[0]: subsystem: 17de:7128, board: Kworld/Tevion V-Stream Xpert TV PVR7134 [card=59,insmod option]
[ 12.108898] input: saa7134 IR (Kworld/Tevion V-Str as /devices/pci0000:00/0000:00:1e.0/0000:02:04.0/input/input5
[ 13.104060] saa7134 IR (Kworld/Tevion V-Str: unknown key: key=0x03 raw=0x03 down=1

ok, you card is found and identified, let’s do some testing without mythtv for the meantime

6) sudo apt-get install xawtv
this installs the tv program, click /Applications/Sound & Video/XawTV, you see the xawtv screen, right click and set video source to ‘composite1’, you should see the TV live, if you connect an audio cable from the card’s audio out port to your pc’s audio in, you should hear the sound, if no sound, play with the volume control, look for PCM/line in, do some tinkering there until you heard the sound, however we are not going to use this sound from line in port of pc for mythtv.

up to this point, our hardware/software for the TV is up, let’s install mythtv:

7) sudo apt-get install mythtv

8) click System/Adminstration/MythTV Backend Setup
basically the audio has to be set to dsp1
9) click Applications/Sound & Video/MythTV FrontEnd
audio has to be set to dsp
10) let’s try a remote FrontEnd
as long as the password for the mythtv is correct, this does not require too much setup, audio is different from #9

more on 8 to 10 when I’m free.

Note: just tried a new PCI TV board, it is very similar to this one:

At back of the card, it says ITO23 REV:4E
took a while to figure out: card=79 tuner=43
