Hello everyone

When i try to "scan for channels" I get the message "failed to open card" followed by an floating point exception. I am using a Plextor TV402U.

Does anyone know how to fix this ?

You might want more details on what I did so here it is.

- Auto Install(I selected "use default i586 set". I dont know if that is correct but I dont think it is related to my problem)

During the setup I select the following.

1. General
Global Backend Setup
TV format : PAL-BG
VBI format : PAL teletext
Frequency table: Europe-west

2. Capture card
Capture card Setup
Card type : USB MPEG-4 encoder box (Plextor ConvertX, etc)
Default Input : Tuner

3. Video Sources
Video Source Setup
Videosource name : Kabeltv
XMLTV listing grabber : Denmark
Click "Finish" and ALT-tab to xterm.
Follow the XMLTV-setup
ALT-tab back to setup

Input Connections
[GO7007:/dev/video0] (Tuner)
Video source: kabeltv
I select "Fetch channels from Listing source"

ALT-tab to the xterm
I notice it says
“Connected to database ‘mytconverg’ at host: localhost
QComboBox:setCurrentItem: (unnamed) Index 1 out of range
QComboBox:setCurrentItem: (unnamed) Index 1 out of range
Using runtime prefix = /usr”
But I guess it is okay anyway since it continues with the download.
I am very patient and wait for “mythfilldatabase run complete”
ALT-tab back again

Hit FINISH but goes back to run “Scan for channels”
In "Scan type" it says “failed to open card”. I try to select Video Source. Setup exits and I get the following in the xterm:

“SelectSetting:setValue(): invalid index 31
SelectSetting:setValue(): invalid index 31
QComboBox:setCurrentItem: (unnamed) Index 1 out of range
/usr/local/bin/Knoppmyth-run: Line 369: 7531 floating point exceptionsu - $USERNAME –c sh –c “DISPLAY=:0.0 mythtv-setup””

I continue setting up mythweather with locale code “da” … is this the correct code for Denmark ? …I quess it might be DK or maybe 1030
Anyway looks like it starts updating xmltv….
The last line says “removing bad characters at /usr/bin/tv_grab_dk line” didnt have time to see the linenumber.

Mythtv start up.

I go to “Watch TV” but get only green static. Make sense since I didn’t succeed in “scan for channels”

System status – listing status – Mythfilldatabase ran but didn’t insert a …

I exit from mythtv and opens an xterm. Run Gorecord to verify that the Plextor is installed correctly … and it works just fine.

Any ideas about what I am doing wrong?

Did you shutdown the backend before entering mythtv-setup?

Setup is started automatic after first boot so I assume the backend is not started at this point.

Anyway I have tried stopping the backend manually and entering setup. Same thing happens.

I did get a little further but still lack sound and TV looks like slow-motion.

Any pointers to how I fix the playback-speed and the sound will be appreciated.

Here is what I did:

Auto Install

During the setup I select the following.

1. General
Global Backend Setup
TV format : PAL
VBI format : PAL teletext
Frequency table: Europe-west

2. Capture card
Capture card Setup
Card type : USB MPEG-4 encoder box (Plextor ConvertX, etc)
Default Input : Tuner

3. Video Sources
Video Source Setup
Videosource name : Kabeltv
XMLTV listing grabber : Denmark
Channel frequency table: europe-west
Click "Finish" and ALT-tab to xterm.
Follow the XMLTV-setup
ALT-tab back to setup

Input Connections
[GO7007:/dev/video0] (Tuner)
Name : Plextor Tuner
Video source: kabeltv
I select "Fetch channels from Listings source"

ALT-tab to the xterm
I am very patient and wait for “mythfilldatabase run complete”
ALT-tab back again

I DON’T scan for channels since it throws an exception; see the first post in this thread.

Hit FINISH

Channel Editor
For each channel I select:
Channel Number: Just the number that fits the order on my TV.
TV Format: PAL
Hit Next
Enter the frequency in Hz.
Hit ESC to Exit

MythTV starts up.

I go to Utilities/Settings->Setup->TV settings->Recording Profiles->USB Mpeg(Plextor ConvertX, etc).
I setup Default, Live TV, High Quality and Low Quality to 480x384. I know this should not be necessary but I don’t want to push my luck right now.

I go to Watch TV. I now get a picture but it does look like it is in slow motion and I am not getting any sound. If I playback a CD then I do get sound.

Any pointers to how I fix the playback-speed and the sound will be appreciated.

Best regards

Okay. I tried changing audio device to DSP0, DSP1, DSP2 and DSP3.

A bit strange but if I set it to DSP or DSP0 then TV plays at half speed and I get “NVP:AddAudioData():p3 Audio buffer overflow. Audio data lost” in the xterm. With DSP2 and DSP3 I get no Audio but TV plays at the correct speed.

I notice that even when Audio Device is set to DSP1 then the following lines appear in the XTERM.
Opening Audio Device
Opening OSS Audio Device /DEV/DSP

Shouldn’t that be /DEV/DSP1 since that is what I selected in the setup of the backend ?

Hi

I think you have to look inside /dev directory ... /dev/dsp is a link to dev/dsp1 I think ... look to output of "dmesg |grep -i dsp" or "tail -n 300 /var/log/messages"

only use small character for /dev/dsp ... case sensitive names!

I have some strange problems sound with my siemens dvb-c card with analog module ... video running on analog channels ... no switch digital channels ... livetv no more video stops working noc quit with ESC ... no restart because MythTV remembers last channel
