Post subject:  PVR-150 displays just static (tuner not recognized?)
hi y'all,

yesterday, i received a large package. inside it, i found a glorious to-become-htpc:
- Asus Pundit P1-PH1
- Samsung Spinrite somethingsomething rather large hd
- cpu, ram
- PVR-150

i put it all together, threw in a dvd writer and fired the thing up. of course, loaded with a knoppmyth cd.

the installation process went quite okay and in about 20 minutes i had the mythtv frontend in front of me. the first thing i wanted to test was the tv reception, so i went to 'television' and saw nothing but static / snow.

i confess: sometimes i can be naive, but i think there's something wrong. what could it be? for 24 hours straight i've been trying to get the thing working. countless re-installs (even once a windows install (which proved that the card isn't broken by the way)), irc chats, google searches.... nothing has helped me out.

so here is my last resort: a post to the official knoppmyth© forums. a loud cry for help. a deep rooted craving for satisfaction. your boyscout duty for today... could anyone help me to get my system working? it's been my dream for about 6 months now and i hate the fact that the pvr150 doesn't work.

oh and by the way: i've got all the settings (frequency tables, pal etc) done right. i'm absolutely positive. and i'm using knoppmyth R5B7.


this is some info i got from some log... i hope it can help solving the problem.

How strange. This is like the issue that has been cropping up with the PVR-500s, try forcing the tuner type to 50 to see if it works. Search on PVR-500 for more details.

I can confirm that I was having the exact same issues as the previous poster
I have a PVR-150

As was suggested editing
/etc/mythtv/modules/ivtv
add "options ivtv tuner=50"
(50 for first tuner being prv-150) after the commented lines

Now my tuner is working. Thanks for the suggestion. I've been pulling my hair out all weekend.

As I posted in another thread the common theme from people having problems like this seems to be here:
Quote:
kernel: tveeprom 0-0050: tuner model is TCL M2523_3DB_E (idx 113, type 4)

This seems to be a reversion either in the IVTV driver code or the MythTV backend code. There was a problem when the Samsung tuners first came out with them being identified as "type 4" and any tuner identified as "type 4" being taken as "no tuner found". The problem was subsequently fixed but seems to have become "unfixed" since then. :?

Post subject: 
thank you all for answering. it seems to be a problem i can't fix.

anyways, after such a long time of searching for a good answer (getting my good old rsi playing up again) i've given up getting knoppmyth to work. it's a shame, because i prefer free software over commercial software.
i've installed windows xp with mediaportal now and it works like a charm. the only thing i don't like about it is its resource usage and the fact that it records in msdvr format. but i can transcode the recordings anyways.

I had these same issues with only recieving static on my tuner card even though it would work on XP... I returned the "defective" pvr-150 card for a replacement and the new card worked fine... sucks but cool that it works now.

I'm having a similar problem - built a Pundit system with R5C7 over the weekend, and used a PVR-150 and a PVR-150MCE. The MCE works fine, but the other (with the remote) gives me the tuner not set error.

I'm not sure how to get the "options ivtv tuner=50" to apply only to the ivtv1 device, and haven't seen anything in the forums that help me. Editting the ivtv1 file in /etc/mythtv/modules didn't seem to do anything...

Do step 4 from the CompileIvtv page on the wiki: http://www.knoppmythwiki.org/index.php?page=CompileIvtv

That ought to get you sorted out, but there's more troubleshooting info here if you need it: http://www.knoppmythwiki.org/index.php?page=BlackScreenWatchingTV

Well I followed those steps, and did successfully recompile ivtv, but I still coluld not get the tuner type option to apply to only one card at a time. Since one card is tuner type 47 and the other 50, I could only ever get one card working at a time.

I worked around this by swapping in another PVR-150 so that I had 2 like tuner types, but I'd still like to understand why I couldn't get a tuner type option to apply to only once or the other card.

Post subject: 
You can specify multiple types seperated by a comma e.g "47,50", and it will be applied to the cards in order. The first one to card #0, the second to card #1, and so on.

You may also want to try the 0.4.6 prerelease mentioned here recently.

I seem to recall having this same problem, and found a reference to renaming tuner.ko to tuner.ko.orig, as it sometimes get placed into two places. One of them has to be renamed as I recall, and the snow/static problem should dissappear.

That's what the "step 4" mentioned above does.

Changing file names didnt work for me but the type 50 change did.

EDIT: I was wrong it did takes both not just one or the other.

You probably need an even more recent version of the driver (0.4.6) as Hauppauge continues to play musical tuner chips with it's boards.

- See the log file diagnostic page mentioned above to see if it is(was) unidentified in the log files.

- See the compile ivtv page and follow the procedure to upgrade to 0.4.6. I've been promising myself that I'll update the directions all week, but for the moment you'll need to take poetic license with them (0.4.4 -> 0.4.6, new location for the firmware described on the linked firmware page). Don't be intimidated by all the detail, it's actually there to make the process safer.

I've updated the CompileIvtv directions for the 0.4.6 release and corresponding firmware.
