Hi.,

I just finished building a PVR system and was having tv-out problms with knoppmythR5A16.

My setup is:

Old Compaq Deskpro (800 Mhx p3)
120G Seagate Barracuda IDE hdd
Hauppauge PVR350 with grey remote

NB: My TV does not have composite or S-Video ports. It just has a 75 Ohm coax port. Thus, I purchased this RF modulator at
http://www.radioshack.com/product.asp?c ... =15%2D2526) I have the tv-out coax port of this RF modulator connected to the TV's coax port using a coax cable, and the composite (audio & video) ports connected to the composite audio-video ports of the Hauppauge PVR-350's 9 pin DIN connector (I have not connected S-Video, is this necessary?).
Pics are at:

I installed knoppmyth. That worked out okay. It can retrieve data-direct stuff from my account there and render it accordingly. I can see picture in the monitor. I tried to get tv-out to work using the howto given below:

http://www.knoppmythwiki.org/index.php? ... stallation


I got a little confused about the pci bus hexadecimal thing, but here's what I did:

my edited /etc/mythtv/modules/ivtv is here:
http://www.ph.utexas.edu/~daneel/knoppmyth-ivtv/ivtv

The driver compiled and installed okay

I got the following is the PCI BUS output if lspci:

lspci|grep MPEG gives:
0000:02:09.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)

Here is my pvr350 XF86Config-4 file:

http://www.ph.utexas.edu/~daneel/knoppm ... g-4.pvr350


Did I do the BUS ID section right?

Also, the howto says to look for the fb device file name in /var/log/messages. I did not find any entries with "TV-out" in them. my /dev/ directory had device file from fb0 to fb7. I tried fb0 first.
With the settings above, not only did my tv-out not work, but my monitor screen froze up during boot (no tv-out, just static on tv)

I booted into a knoppix cd, mounted the /dev/hda1 partition and restored the original XF86Config-4 file and rebooted into knoppmyth. Checking /var/log/messages showed a large # of of "ivtv-fb" entries. I forgot to upload them, but if they're important, I'll get them.

I'd welcome any advice on this matter. I probably just messed up my XF86Config-4 file (unless hooking it up to an RF Modulator won't work here). In any case, I'd be mighty grateful for some help.


It'd be great if I could get mythtv to work here. Then I'd not have to use windoze (which I hate) and I'll post details of my setup in the forum.


Thanks for your attention
Regards,
AR

Update: My tv-out still doesn't work, but I followed the howto at:

http://mysettopbox.tv/phpBB2/viewtopic. ... 6317#36317
after reinstalling knoppmyth.

My RF modulator is receiving a signal now (LED glows green) and the appropriate channel in my tv now shows horizontal grey bars and is frozen.

I disconnected my monitor and my pvr is still running (X-server has crashed though) and I can access it over my LAN using ssh. I'd appreciate any help at this point.

Thanks,
AR

Hi hari_seldon99,

Maybe I can help a little as I also have a Compaq Desktop Pro only it is ~700 mhz :( 126meg me 16 gig hd PVR-150

Ok with the rf modulator, I got mine at Kmart ~$25 +tax of course. Works well and has three ports in. However, I am not using it on the pvr-150 (not an option) but do use it on my "production" machine with the 350.

The getting tv out of the 350 is a bit touchy. One of your best tools is the ssh and come in from a different box. Take it in two steps, tv out first then the desktop out on tv also. The latter can be a pain.

By using the remote shell, as root, you can play with the xserver settings to get things going. First you do a "killall gdm". Go in and do your edits in the XF86Config-4 file, I think there are a couple of sample files you can build from. Make a backup copy of what you have as there will be information that you will require. Like the video drive, mine uses the mga.

The key is as a remote login, you can do a "startx" and watch the error messages. When all is well, it may complain about fonts and things however it won't return to the cmd prompt. You have to do cntrol C to terminate, however at this point you can do "gdm" and bring the system backup up. There is also a check box in the tv settings to enable tv out from the pvr-350.

The Bus ID doesn't come into play until you get ready to send to the tv however the frame buffer is needed. You may not need to make the vga=normal in the lilo, unfortunetly, I can't say for sure. End result is when you play tv or a recording, the computer screen will go black nd the tv should output via the modulator. Us a recording for testing as it takes the cache out of the equation.

At least this may give you a bit of an insite?

parts of XF86 file... This is the meat of my XF86Config file using a pvr-350

#6June2005
Section "ServerLayout"
Identifier "XFree86 Configured"
# Screen 0 "TV Screen" #everything to tv
Screen 0 "Screen0" 0 0 #tv out only
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "PS/2 Mouse" "CorePointer"
...................
Section "Device"
Identifier "Hauppauge PVR 350 iTVC15 Framebuffer"
Driver "ivtvdev"

### change fb1 to whatever number you got in the previous section
Option "fbdev" "/dev/fb1"
Option "ivtv" "/dev/fb1"
### change the busid to whatever is reported by lspci. Note that
### output of lspci is hex, so add a preceding "0x" to the BusID
BusID "0:9:0"
EndSection
................................................
Section "Screen"
Identifier "TV Screen"
Device "Hauppauge PVR 350 iTVC15 Framebuffer"
Monitor "NTSC Monitor"
DefaultDepth 24
DefaultFbbpp 32
Subsection "Display"
Depth 24
FbBpp 32
Modes "720x480"
EndSubsection
EndSection

A potential area of trouble is with the audio, the Compaq uses snd_es1688 which is discovered properly with "alsaconf" "alsamixer " sets the values for output. Audio from the 350 is a fixed level and not controlled by the F10 - F11 anyway.

If this doesn't help, maybe I can dig up some more tomorrow
Mike

Thanks for your reply.


Actually, I managed to get tv-out to work this evening by mooching off of the XFree86Config-4 file of another chap on the mythtv-users irc channel. The main problems were that my "/dev/fbX" was not set correctly, and I made a typo while copying the compiled ivtv driver to the modules tree. I corrected it and it all works now!

But my remote does not work :(

I pressed a few keys and the IR port of my TV flashed (is it supposed to do that?). I've connected the infrared antenna supplied in the package of the Hauppauge pvr350 to the "ir" port of the card, and I have the Hauppauge grey remote. According to knoppmyth documentation, the lirc config files default to the hauppauge grey remote, but here it doesn't work. Could it be due to interference from the tv I wonder? How do I determine this?
