Yeah, here's what I get:

Here's the ivtv file I use:

remove ivtv /sbin/modprobe -r --ignore-remove ivtv && /sbin/modprobe -r saa7115
&& /sbin/modprobe -r msp3400 && /sbin/modprobe -r tuner

(keep in mind I use a serial remote instead of the pvr-350's i2c receiver, so ignore the lirc_serial stuff)

At this point I think someone who knows more then I might be better suited to help you, but in my "professional" opinion (for what that's worth) it looks like some major stuff isn't initing. Do you have all that modprobe stuff in your ivtv file?

Post subject:	PVR350 Not Tuning All Else works fine
I installed KnoppixMyth on an Athlon XP 1900 system, ASUS Mobo, 300 GB drive, 512 MB Ram. Thanks to serveral good articles and some trial and error I have everything working now, at least all the basic stuff, including using hardware encoder TV out. The major problem remaining is that I cannot tune cable channels. When I watch TV I get a black and white image of some channel that is very distorted or noisy and no sound. I can change channels with the remote and the overlays work fine but the tv image remains the same as far as I can tell. I searched repeatedly and this seems to be a tuner type problem. I suspect that my tuner is not being properly recognized but I have been unsuccessful in finding a solution. My pvr350 was purchased in October 2003 and has worked fine in a windows box since then. My tuner type seems to be determined as type 0. But things I would expect to see like the acknowledgement of the fm tuner does not appear. Here is the output from a suggestion I found in another message: ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.2.0 (rc3j) loading ivtv: Linux version: 2.6.11.9-chw-2 SMP preempt 586 gcc-3.3 ivtv: In case of problems please include the debug info ivtv: between the START INIT IVTV and END INIT IVTV lines when ivtv: mailing the ivtv-devel mailinglist. ivtv: Autodetected WinTV PVR 350 card ivtv: Found an iTVC15 based chip ACPI: PCI interrupt 0000:00:09.0[A] -> GSI 9 (level, low) -> IRQ 9 ivtv: Unreasonably low latency timer, setting to 64 (was 32) ivtv: XXX PCI device: 0x700e vendor: 0x1022 ivtv: i2c attach [client=tveeprom,ok] ivtv: i2c attach [client=(tuner unset),ok] tuner 0-0061: chip found @ 0xc2 (ivtv i2c driver #0) msp34xx: ivtv version msp34xx: init: chip=MSP3448W-A2, has NICAM support, simple (D) mode, simpler (G) no-thread mode msp34xx: $Id$ compiled on: May 24 2005 00:43:28 ivtv: i2c attach [client=MSP3448W-A2,ok] saa7115: starting probe for adapter ivtv i2c driver #0 (0x10005) saa7115: detecting saa7115 client on address 0x42 saa7115: writing init values ivtv: i2c attach [client=saa7115[0],ok] saa7115: status: (1E) 0x00, (1F) 0xc0 ivtv: Tuner Type 0, Tuner formats 0xe0b577c0, Radio: no, Model 0x00000000, Revision 0x00000001 ivtv: PAL tuner detected ivtv: NTSC tuner detected ivtv: SECAM tuner detected ivtv: Radio not detected saa7127: Ignoring new-style parameters in presence of obsolete ones saa7127: video encoder driver version V 0.3 loaded saa7127: detecting saa7127 client on address 0x88 saa7127: Selecting NTSC video Standard saa7127: Selecting S-Video+Composite saa7127: Turn WSS off saa7127: Widescreen Mode 4:3 Full Format saa7127: Selecting Normal Encoder Input saa7127: Enable Video Output ivtv: i2c attach [client=saa7127[0],ok] ivtv: Encoder revision: 0x02040011 ivtv: Decoder revision: 0x02020023 ivtv: Configuring WinTV PVR 350 card with 9 streams ivtv: Create DMA stream 0 using 256 16384 byte buffers 4194304 kbytes total ivtv: Registered v4l2 device, streamtype 0 minor 0 ivtv: Create DMA stream 1 ivtv: Registered v4l2 device, streamtype 1 minor 32 ivtv: Create stream 2 using 40 52224 byte buffers 2097152 kbytes total ivtv: Registered v4l2 device, streamtype 2 minor 224 ivtv: Create DMA stream 3 using 455 4608 byte buffers 2097152 kbytes total ivtv: Registered v4l2 device, streamtype 3 minor 24 ivtv: Create stream 4 ivtv: Registered v4l2 device, streamtype 4 minor 64 ivtv: Create DMA stream 5 using 16 65536 byte buffers 1048576 kbytes total ivtv: Registered v4l2 device, streamtype 5 minor 16 ivtv: Create stream 6 using 1024 2048 byte buffers 262144 kbytes total ivtv: Registered v4l2 device, streamtype 6 minor 228 ivtv: Create stream 7 ivtv: Registered v4l2 device, streamtype 7 minor 232 ivtv: Create DMA stream 8 ivtv: Registered v4l2 device, streamtype 8 minor 48 ivtv: Setting Tuner 0 tuner 0-0061: type set to 0 (Temic PAL (4002 FH5)) saa7115: decoder set input (4) saa7115: now setting Composite input ivtv: Setting audio matrix to input 3, output 1 ivtv: Switching standard to NTSC. ivtv: ivtv_enc_thread: pid = 2291, itv = 0xe0c2faa0 ivtv: ivtv_dec_thread: pid = 2292, itv = 0xe0c2faa0 saa7115: decoder set norm NTSC saa7115: set audio: 0x01 saa7127: Setting Encoder Video Standard saa7127: Set NTSC Video Mode saa7127: Selecting NTSC video Standard ivtv: Initialized WinTV PVR 350, card #0 ivtv: ==================== END INIT IVTV ==================== Any help is appreciated.

Hmm, if you think you have the wrong tuner type you might try <code>tail /var/log/messages -n 1000 \| grep tveeprom</code> and see what tveeprom spits out. That should tell you what tuner type you have. You could then try setting your tuner type explicity in /etc/mythtv/modules/ivtv Another suggestion: black and white fuzzy screen can also occurr if you accidentally have your card set up for PAL when it should be NTSC (or vice versa) in /etc/mythtv/modules/ivtv.

This can also happen if you have the wrong frequency set selected (e.g. - us-cable vs. us-cable-hrc) Run mythtv-setup and check on the 3rd page under "General".

When I enter tail /var/log/messages -n 1000 \| grep tveeprom I get the following: Sep 14 21:58:28 mythtv kernel: ivtv: i2c attach [client=tveeprom,ok] and nothing more. In my unmodified /etc/mythtv/modules/ivtv the "options tuner type=X" was remarked out. When I removed # sign and set it to 0 or 2 or 39 The watch TV screen is completely black. When I attempt to change channels the overlays show but the tuner is obviously not working. The mythtv-setup is set to NTSC and I don't see anything in /etc/mythtv/modules/ivtv that indicates otherwise. Anything else I should try? I've sort of figured that a card that was two years old did not use the "new tuner" I've read about. Should I try the latest ivtv driver? srahrens wrote: Hmm, if you think you have the wrong tuner type you might try <code>tail /var/log/messages -n 1000 \| grep tveeprom</code> and see what tveeprom spits out.

yeah channel change is deffinately pokey. You'll find this on any PVR. my mythbox changes channels about every 5 seconds or so. Just for reference, my tivo only does slightly better (probably about 3). Cool, glad we were able to get things working for you.
