Re: HVR 1600 Distortion
Try a DTV STB or VCR with an RF out on channel 3. Your card might not be bad. Your signal looks overdriven from the new MPEG you sent. I'll discuss more when I'm not typing on my smartphone's tiny little keyboard.

Is it because the analog portion goes through a different set of chips? Yes, the analog portion of the card has a completely separate tuner and demodulator. Don't get me wrong, it's possible that this is a driver issue, but given Andy has the exact same can tuner on his board it probably makes sense for you to do a sanity test of the hardware before any more time is spent investigating the software.

Re: HVR 1600 Distortion
Thanks for the response! Replies are in line.

I know I need to include more information but I'm not sure what to include. Any help would be appreciated. 1. Would you say the distortion is something you would possibly encounter on an analog television set, or does it look uniquely digital? On systems with a long uptime and lots of usage, MPEG encoder firmware could wind up in a screwed up state giving weird output image. Simple solution in this case is to reboot. I'm not sure if I would classify it as uniquely digital. The distortion happens across most of the screen with it being concentrated in the top third. Additionally shows that include black bars the top black bar is seemingly stretched and the image seems like the colors are over-saturated where they colors are brighter. Rebooting had no effect :( 2. Have you ensured your cable plant isn't affecting signal integrity? http://ivtvdriver.org/index.php/Howto:Improve_signal_quality The cable plant hasn't changed the signal strength or integrity as far as I know. 3. Does this happen with only the RF tuner or only CVBS or only SVideo or more than one of them? If the problem is only with RF, then it could be an incoming signal distortion problem. Do you have cable or an over the air antenna for analog RF? I only have input for the RF tuner. I have cable for analog RF. 4. What does v4l2-ctl --log-status show as your analog tuner? Not sure what you mean so I've included the full output: # v4l2-ctl -d /dev/hvr1600 --log-status Status Log: cx18-0: = START STATUS CARD #0 = cx18-0: Version: 1.2.0 Card: Hauppauge HVR-1600 tveeprom 3-0050: Hauppauge model 74041, rev C6B2, serial# 898361 tveeprom 3-0050: MAC address is 00-0D-FE-0D-B5-39 tveeprom 3-0050: tuner model is TCL M2523_5N_E (idx 112, type 50) tveeprom 3-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 3-0050: audio processor is CX23418 (idx 38) tveeprom 3-0050: decoder processor is CX23418 (idx 31) tveeprom 3-0050: has no radio, has IR receiver, has IR transmitter cx18-0 843: Video signal: present cx18-0 843: Detected format: NTSC-M cx18-0 843: Specified standard:NTSC-M cx18-0 843: Specified video input: Composite 7 cx18-0 843: Specified audioclock freq: 48000 Hz cx18-0 843: Detected audio mode: mono cx18-0 843: Detected audio standard: BTSC cx18-0 843: Audio muted: no cx18-0 843: Audio microcontroller: running cx18-0 843: Configured audio standard: automatic detection cx18-0 843: Configured audio system: BTSC cx18-0 843: Specified audio input: Tuner (In8) cx18-0 843: Preferred audio mode: stereo cx18-0 gpio-reset-ctrl: GPIO: direction 0x3001, value 0x3001 tuner 4-0061: Tuner mode: analog TV tuner 4-0061: Frequency: 175.25 MHz tuner 4-0061: Standard:0xb000 cs5345 3-004c: Input: 1 cs5345 3-004c: Volume: 0 dB cx18-0: Video Input: Tuner 1 cx18-0: Audio Input: Tuner 1 cx18-0: GPIO: direction 0x3001, value 0x3001 cx18-0: Tuner: TV cx18-0: Stream: MPEG-2 Program Stream cx18-0: VBI Format: Private packet, IVTV format cx18-0: Video: 720x480, 30 fps cx18-0: Video: MPEG-2, 4x3, Variable Bitrate, 660, Peak 660 cx18-0: Video: GOP Size 15, 2 B-Frames, GOP Closure cx18-0: Audio: 48 kHz, MPEG-1/2 Layer II, 384 kbps, Stereo, No Emphasis, No CRC cx18-0: Spatial Filter: Manual, Luma 1D Horizontal, Chroma 1D Horizontal, 0 cx18-0: Temporal Filter: Manual, 8 cx18-0: Median Filter: Off, Luma [0, 255], Chroma [0, 255] cx18-0: Status flags: 0x0021 cx18-0: Stream encoder MPEG: status 0x, 0% of 2048 KiB (64 buffers) in use cx18-0: Stream encoder YUV: status 0x, 0% of 2048 KiB (16 buffers) in use cx18-0: Stream encoder VBI: status 0x, 0% of 1015 KiB (20 buffers) in use cx18-0: Stream encoder PCM audio: status 0x, 0% of 1024 KiB (256 buffers) in use cx18-0: Read MPEG/VBI: 3507263488/15001920 bytes cx18-0: == END STATUS CARD #0 == 5.

Have you recently installed new hardware in the subject computer? Of most interest are adapter cards with cables coming off of them and cards very close to the HVR-1600. EMI can be picked up by the HVR-1600's board traces that are not shielded. 7. Does the distortion look like loss of horizontal line sync and happen only near very bright parts of the image on the left edge? If it does, the baseband video signal level is too high. 8. Care to post a short image in a paste bin or email a small MPEG to me?

HVR 1600 Distortion
