Hello I just registered. I just bought a PVR-150, installed KnoppMyth R5A15, and seem to be having some trouble getting the backend configured and running properly. Im not really sure what to try next.

I followed the wiki steps http://knoppmythwiki.homelinux.org/index.php?page=HauppaugeOneFiftyInstallation but hit problems with the mixer_input=2 line.

This post seemed helpful so I basically followed it, but I noticed my tuner had #39 so I switched that.
http://mysettopbox.tv/phpBB2/viewtopic.php?p=23905&

I copied the firmware off the cdrom and setup a symlink for the encoder (not for a decoder), from here http://ivtv.writeme.ch/tiki-index.php?page=PVR150-500Firmware

I have tried both 0.3.3u and 0.3.3s.

Here's my /etc/mythtv/modules/ivtv (I eliminated the /etc/modprobe.d/ivtv file in favor of this one):

Two lines in the dmesg have me concerned, this one which Im not sure where to find different encoder versions since that came from the cdrom:
ivtv: Encoder Firmware may be buggy, use version 0x02040011

and this one at the end:
ivtv: i2c client addr: 0x43 not found![/url]

Looking at that dmesg I see
ivtv: i2c attach [client=cx25840[50],ok]

so I tried an ivtv with tuner=50 but no diff.

Also here's some of those allocation errors Im seeing:
ivtv: ENC: VBI got (0) needed 104 bytes for stream 2, only 12568192 differ by (-12568088) bytes

Hi There,

I wound up re-doing my box and following own instructions last night. I couldn't get things to work with 3.3u either, so I started over and used the exact rev the gentleman who wrote the PVR500 instructions used:



That seemed to work very well. The only issue that i had with the 3.2r release as that I have a line of noise at the very top of the picture on most channels, and I did net to go in to my TV settings and set all my resolutions to 720x480. I believe the resolution issue is fixed in later drivers but I couldn't get the stability I need.

So give it a try with the 3.2r drivers and the docs I added, mine came right up and all I needed to do was adjust the resolution to get all the picture back.

-Jeff

PS - I found that the docs in the link about the 500 were easier to understand than those in the Wiki. I started with the wiki originally foor my PVR-150 and then ended up using the 500 docs from scratch, which the changes I posted. Both had hints and tips but in th eend the ones for the 500 worked the easiest for me.

The line of noise at the top is data in the vertical blanking interrupt. You can hide it by adjusting the overscan in mythtv, I believe.

And yeah, the PVR-500 instructions worked well for me too. Kudos to ralph.

-brendan

Thank you for the reply. I will download and try "3.3r". I also just reverted the encoder firmware to match that post, i.e. not using the HcwFalcn.rom from the cdrom, instead using the extracted files from pvr48wdm_1.8.22037.exe
-- are you using those?

And...when you reverted the driver, did you do any make clean type statements or simply make install again?

Typically, each time I downloaded a new ivtv package, the directory was a new one, so there was no need to make clean. You'd only really need to do that if you'd compiled that version, modified the source and wanted to compile again.

Just a side note: IIRC, some of the 3.3.2[a-z] versions had a problem with not properly pushing out the tuner.ko file during make install.

I had to work around that by finding the tuner.ko files that already existed, renaming them, and copying the one from the that build to the same places, even after the make install.

-brendan

Im using 0.3.2r now and some progress has been made. The mythbackend does not seem to be generating the alloc errors. However,

the mythfrontend, when selecting Watch TV, initially shows the Guide full screen with the upper left corner having a 4 x 4 black area with a 1 inch band at the top of it that has 3 fuzzy thumbnails of thoroughly distorted video. Sound can be heard but is choppy, and may be helium-like (I should hook up better speakers and see).

When I press escape it goes full screen and I can see the cable station, but its in a really slow motion with occassional motion freezes. Ideas?

Are you using the nvidia X driver? How well do DVDs play?

-brendan

The play screen is looking better after I reduced X cfg to use 640 x 480 and after chging the mythfrontend play settings to 720x480. The first screen after clicking Watch TV is still a problem: upper right corner yuch.

This is an nvidia board but it didnt come with the tvout (which I have ordered), so in the meantime I was trying to use a Radeon 9200 based PCI card which has an S-Video out. In X I have this set as driver "vesa".

Before I move the thing up to the TV with the S-vid I wanted to try and get the remote working. I made it through all your steps but I dont see any activity in the messages tail when pushing the remote under irw -- any suggestions how to diagnose?

Update: remote is working now. I did need to add lirc_i2c to /etc/modules on this KnoppMyth-created system.

I cant type "mythsetup" to reconfigure the backend IP address (which is dhcp but oh well).

Still have the initial 4x4 screen prob. I wonder if that box is a special resolution I need to add to my X cfg, like 180 x 120 or something tiny.

There is no mythsetup, it is

Remote has stopped working. It seems lircd dies everytime I run irw.

root@Mythtv:~# lircd -n
lircd 0.7.1pre2[4180]: lircd(any) ready
lircd 0.7.1pre2[4180]: accepted new client on /dev/lircd

lircd 0.7.1pre2[4180]: default_init(): No such device
lircd 0.7.1pre2[4180]: caught signal
Terminated

Still googling for a solution. Any ideas?

So is the final solution to this problem reverting to an older version of ivtv? It just appeared to me when I started using the 0.3.5x branch, but not 0.3.5 itself.

I gave up on lirc and bought a $19.99 (includes shipping) wireless RF keyboard & mouse from chiefvalue.com, which just use the ps/2 ports. I wanted to spend my time on other aspects of the mythtv box. Kbd works fine but I'm keeping my eye out for a smaller one, and I read elsewhere that others have bought a wireless Infrared (IR), not RF, keyboard, then they bought a 'learning' remote from walmart, and they taught their remote using their wireless keyboard: they can then use that remote for other devices too or fallback to the keyboard for internet browsing on the myth box etc. But again avoiding lirc alltogether.
