Well so far, I've managed to get much farther than I expected for someone new to X based linux (usually I just use the command line, for routers/samba boxes, so I'm new to the wonders of X :<)

1) I've done the "copy XF86Config-4 to XF86Config-4.orginal" and "copy XF86Config-4.pvr350-tvout to XF86Config-4". This mostly works, but I still have the following issues:
a) TV out works for TV, but is very jittery but no audio.
b) However, in the Playback Options, if I enable the PVR350 option, I *do* get audio out, but no video
c) I have to assume this is because the video device is /dev/video16 but so far as I know from the other options I set, its actually /dev/video. The system does have an onboard video card that works, so I'm not certain how to determine if the PVR is in fact /dev/video or /dev/video1, etc. I know that the TV in is working, as I set up a manual 2 minute record, and when going into "view recordings" it does show the PIP size window with the video, so its obviously still getting the video in, just not out.

2) Since I've copied the XF86Config, I've lost the use of my keyboard in X. I did see a few posts where people indicated they had to "add sections for keyboard and mouse". But in comparing the file to the ".original" I made, plus the XF86Config-4 on a second system I'm testing with, it all seems to be identical for the keyboard/mouse (no mouse attached though). I kind of expected that if I swapped configs back, that I'd get the keyboard back, but lose the TV out. Well, I certainly lose the TV out, but still lose the keyboard. I can however, stop X from loading (or manage to start a shell anyways) and the keyboar works fine there - so its not a connection issue. Main problem here is, that I need the keyboard to change the /dev/video in #1 above because so far as I can tell, none of the buttons on the Hauppauge gray remote are 'backspace', so all I can do is add to the /dev/video16

So hopefully someone can tell me what I'm doing wrong :>

BTW, its worth making a note in case another newbie comes across this in the search for enabling the PVR-350 - when copying the PVR350 config, you do not also get VGA out. This had me quite frustrated, as I was trying to test it on my desk, and move it to the living room once it was working, and I'd keep getting black screens. I finally yarded the works into the living room, and was quite happy with the fact that the TV out was certainly working :> Who knew. I expected I'd have both simultaneously - I don't need it, but that's what I thought I'd get.

No one at all, eh?

1) When enabling the TV out features of the PVR-350, how does one determine on the screen for Playback Options and "Use PVR-350" what /dev/video# device it should be set to?

2) Why does the keyboard not work with the sample PVR350 config provided for XF86?

I have no idea about the keyboard stuff, but if you want everything on the tv from the pvr350 you have to load the ivtvfb driver so X can use the tvout.

Everything *but* viewing TV comes out on the TV just fine. Weather, menus, etc, etc. Only when viewing TV do I get a black screen and audio (with the PVR350 section enabled in Playback Config). Without the section enabled, I get video - but very choppy - and no audio.

Given that I understand that DVD and other stuff won't play out through the TV out on the 350 anyways, I suspect I'll just abandon even bothering to make it work and just finding a video card/montherboard with TV out that matches some other people's configs.

Sounds like you've probably given up on this, but I ran into a similar problem and was able to come up with the solution...

The following is an excerpt from post http://mysettopbox.tv/phpBB2/viewtopic.php?t=697
(see last post from wlemmers)

-----------------------------------------------------------------------------------

The reason for the black screen (with sound) is that the alpha blend is set on the wrong fb device. (myth 0.14 & ivtv 1.9)

In the new knoppmyth release /dev/fb0autodetect has minor nr 1 which myth expects for /etc/fb1.

See the dmesg: Warning: Remapping obsolete /dev/fb* minor 32 to 1

/dev/fb1 is minor nr 32

To solve this delete /dev/fb0autodetect and /dev/fb1 and create a new fb1:
mknod /dev/fb1 c 29 1
chmod 666 fb1
chown video fb1

-----------------------------------------------------------------------------------

also lots of great information from this thread: http://mysettopbox.tv/phpBB2/viewtopic. ... sc&start=0

hope that helps.

I found that the info srahrens provides is extremely helpful, but only for those of use who have two framebuffers (I have an AGP video card with TV out that is fb0, so the screwed up fb1 was causing a problem).

However, there was something else I had to do to get my PVR-350 to properly display (though if you're getting menus, I would think that it would already be working). I had to add some kernel module info. To the file

/etc/mythtv/modules/ivtv

I added these lines at the end:

I'm having similar issues with a black screen while trying to watch TV with my PVR-350. One thing I've found is that I apparently have a card who's revision isn't supported in the 1.9 release.

modprobe tveeprom to see what your card revision is.


This is what I get back from my card:

I don't think it's a revision issue - I also have "model=48132, rev=J323" and my tv-out is working fine despite some occasional instability.

Been a while since I played with this, I bought a PVR-350 a while ago to try with this and gave up after having trouble getting it to work properly (as well as some controller issues with my MB).

Why doesn't PVR-350 support work out of the box yet? I thought Hauppaugue gave these guys some free PVR-250/350's to get work'n with this thing? Why not have an install option that asks if you have a PVR-250/350 and if you have a 350 if you want TV output on it and be done with everything? BAH!

I'm sorry that my personal and professional life doesn't allow me to develop KnoppMyth 24x7. I sorry you don't appreciate the work we've put into this project. I sorry that 95% of the work has been done for you. If you don't like KnoppMyth don't use it.

Um... actually, I'm incredibly happy with what you've provided...

and I do understand that my issues are mostly in finding the correct driver combination... at this point IVTV-0.1.10-pre2-72.whatever works... but the tuner isn't very happpy... but what can I expect when I'm working with alpha software...

I've spent time trying to get a Fedora based myth box up, a gentoo box, and failed with both...

With knoppix, I've been able to record shows with both my 350 and with a BT878 card...

Thank you for the time you do put into this environment.

Yup! I think the KnoppMyth was WAY easy and was extremely happy that it exists. I LOVE the concept and, once my own system is stable (presumably when ivtv is a little more mature), I'd love to start contributing (info, even if not actual, legitimate work).

But I want to make sure that what I suggest and/or do actually makes things better.
