I'd like to say thank you to everyone for this thread. It definitely helped me get further in a shorter amount of time than if I had to figure all of this out on my own. However, if people are experiencing the "watch live tv black screen issue", you may be interested in the following command that I had to execute on my box as root. FYI, the PVR-350 on my machine ended up as fb0:
chmod 666 /dev/fb0
This would probably work for Hans instead of running mythfrontend as root.
Here's a related thread:

larryka, good to hear you got everything going...
ps, JUST FYI TO ALL
i noticed that chris kennedy has released quite a few new revisions of his ivtv driver since he released -41 on 26 feb 2004; they are located in
http://kmos.org/~ckennedy/ivtv/
i continue to use his -41 version without problems (save for an occasional /var/log/message emission regarding dma issues). however, the -41 version is no longer in his top level directory, but it is in
http://kmos.org/~ckennedy/ivtv/old_patches/
specifically at
http://kmos.org/~ckennedy/ivtv/old_patc ... stream.tgz
if anyone has experiences (good or bad) with CK's later versions it would be nice to know what you have found. the changelog as of "today's" version  is interesting... but it's still a little scary to use the latest stuff...
http://kmos.org/~ckennedy/ivtv/osd_stream-84c.diff
one thing for sure is that chris is putting his back into it -- and taking into account that he does not have full documentation for the card nor the on-board devices, he is making great progress.

BUMP since some still are having trouble with X-on-PVR350 and/or getting TV-out to work on the PVR350.
but a question from above...

Tried some time ago, with no success. Since then, I am sticking with 0.1.9 with Matthias's ivtvdev driver and it's been very stable for me.
I follow the ivtv-dev mailing list, but it's nearly impossible to even figure out what exactly they are working on, and how it will affect me (or more generally, MythTV).
I guess I am waiting for some stability in the driver development before I try anything new.

same here. i recently unsubscribed from the ivtv mail list with the thinking that i'll "tune in later" if and when i need to. there doesn't seem to be a strategy of releasing a "stable" version and then continuing development. it's very ad-hoc.

I have followed Laurent's post at the top of this thread to get tv-out working on my PVR350. I had a problem with the modprobe ivtv-fb giving me a lot of errors.

Since fb1 didn't work I tried fb0. I now have tvout on the pvr350 and all my menus and can watch tv but only get about 3 or 4 frames per second with a PIII450. I have seen numerous references to turning on pvr350 in myth but I can't for the life of me find where to set this.
I have most of the tvout threads and this is the one that got me the furthest but I need to get the speed up a little bit.
Thanks
Paul

paul,
keep searching, it's there. right now your system is depending on your (modest) 450MHz CPU to do mpeg decoding. that's why the frame rate is so slow. what should be happening instead is the PVR350's hardware mpeg ASIC should be doing it. that function is enabled by the checkbox you are looking for.

the setting is enabled from the mythtv interface under setup -> tv -> playback it's about the 4th screen or so. there is a checkbox for use pvr350 towards the top of the screen.

Well, I found the setting for use pvr350 but if I select it I get nothing, black screen and no sound. If I deselect it I get jerky sound and video. I have tried with fb0 and fb1, fb0 I get menus and slow playback fb1 I get nothing. The logs are clean thie only problem is "spurious 8259A interrupt: IRQ7" but according to what I have found here this is not a serious issue. When you select use pvr350 you have to select a video device, myth is putting /dev/video16 in here, how do I confirm that this is the correct device?

I did some looking on the ivtv site and found this line of code
dd if=/dev/video of=/dev/video16 bs=64k
when I run this as mythtv I get beautiful full speed video so it seems that the problem is in my mythtv setup.

Thanks for the help, my final problem was permissions for /dev/fb0 I had followed a post that fixed the obsolete fb problem but I followed it so closely that I fixed fb1 while my card is on fb0.
This is a very good thread for getting the pvr350 setup, thanks guys.
The only thing I would add to the thread is to suggest rebuilding the ivtv driver and installing tveeprom.o and msp3400.o for those using R4V4.1 as these don't seem to get setup right by the autoinstall on this release.
I really like the product, much more polished look and feel than anything else I've seen.
Paul

Hi, I'm currently stuck with the initial run of tv_grab_fr --configure. It seems to hang when invoked from mythtv-setup.
I tried to run it manually from console and it indeed hangs after I have answered all the questions about the channels I'm interested in:
Code: Get channels type : CABLE/SAT? [yes,no,all,none (default=yes)] no
Get channels type : CANAL SAT? [yes,no,all,none (default=yes)] no
Get channels type : ETRANGERES? [yes,no,all,none (default=yes)] no
Get channels type : HERTZIENNE? [yes,no,all,none (default=yes)] yes
Get channels type : TPS? [yes,no,all,none (default=yes)] no
I tried the same thing on Win2K with the latest build of XMLTV (0.5.36) and it worked, so the source site is not broken. Since you seem to have fixed a couple of bugs on it, maybe you can give a few hints on what can go wrong within tv_fgrab_fr ? Meanwhile, I'll have a look at the perl code...

No idea... never had this problem before.
If you want, send me a private message with your email, and I'll send you the modified version.
The main fixes are:
- Split titles into title + subtitle for shows that have a "-" in them
- Do a category mapping (fr->en) to provide "decent" colors in the Web interface. This might be a terrible hack, since I suspect there is another way to do this
- I can't remember what else went in there...
