Below is a reposting of an unanswered help request I submited on Feb, 23, 2007. I appened the information from my MythTV request for easy access to the information. ------
I have a PVR-150 and am trying to get a MythTV box working. I have found that after trying to get MythTV working that it was not recording all of my shows. Long story short I ended up testing the card by using cat /dev/video0 > 10min.mpg and playing the result. What I got was just over 7 min though I timed it and recorded it for 10 min (+/- a few seconds). I think I may have the card incorrectly configured. The original post is located at http://mythtv.org/pipermail/mythtv-users/2007-February/167868.html and here is a snippit from dmesg. If any further info is needed feel free to ask. Thanks in advance. -Thymus ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.7.1 (tagged release) loading ivtv: Linux version: 2.6.17-2-686 SMP mod_unload 686 REGPARM gcc-4.1 ivtv: In case of problems please include the debug info between ivtv: the START INIT IVTV and END INIT IVTV lines, along with ivtv: any module options, when mailing the ivtv-users mailinglist. ivtv0: Autodetected Hauppauge WinTV PVR-150 card (cx23416 based) ACPI: PCI Interrupt Link [APC4] enabled at IRQ 19 ACPI: PCI Interrupt 0000:02:07.0[A] -> Link [APC4] -> GSI 19 (level, low) -> IRQ 209 ivtv0: Unreasonably low latency timer, setting to 64 (was 32) tveeprom 2-0050: Hauppauge model 26582, rev E6B2, serial# 9784951 tveeprom 2-0050: tuner model is TCL M2523_5N_E (idx 112, type 50) tveeprom 2-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 2-0050: audio processor is CX25843 (idx 37) tveeprom 2-0050: decoder processor is CX25843 (idx 30) tveeprom 2-0050: has no radio, has no IR remote tuner 2-0061: chip found @ 0xc2 (ivtv i2c driver #0) cx25840 2-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #0) Creative EMU10K1 PCI Audio Driver, version 0.20a, 16:56:49 Sep 13 2006 cx25840 2-0044: loaded v4l-cx25840.fw firmware (16382 bytes) wm8775 2-001b: chip found @ 0x36 (ivtv i2c driver #0) ivtv0: loaded v4l-cx2341x-enc.fw firmware (262144 bytes) ivtv0: Encoder revision: 0x02050032 ivtv0: Allocate DMA encoder MPEG stream: 128 x 32768 buffers (4096KB total) ivtv0: Allocate DMA encoder YUV stream: 194 x 10800 buffers (2048KB total) ivtv0: Allocate DMA encoder VBI stream: 120 x 17472 buffers (2048KB total) ivtv0: Allocate DMA encoder PCM audio stream: 455 x 4608 buffers (2048KB total) tuner 2-0061: type set to 50 (TCL 2002N) ivtv0: Initialized Hauppauge WinTV PVR-150, card #0 ivtv: ==================== END INIT IVTV ==================== Below is the contents of http://mythtv.org/pipermail/mythtv-users/2007-February/167868.html for easy access. ------ Ok, now that things have calmed down from the holidays and stuff I have been able to get back to my MythTV project. Before it got side tracked I found that while MythTV worked it was doing something strange in the way of not recording the whole time alloted. I found that when recording that I was only getting aobut 20 min for a 30 min show. At the time I tohught it was a problem with MythTV. Sence then I tried cat /dev/video0 > 10min.mpg for 10 min (yes I used a timmer) and when I went to view it with VLC on my Powerbook (OSX) it was only 7 min 18 sec long. That scales up to the same 20 min for a 30 min show. Given this it seems I have the card configured incorrectaly. Are there some settings I need to set to get it to properly decode the RCA input lines from my satalite reciver? There does appear to be a few droped frames in the message history of VLC but I do not know if this applies to this problem or not. Below is log from the VLC program in the hopes that it points to a reason for the problem as there are a lot of warnings in there. main debug: CPU has capabilities AltiVec FPU main debug: looking for memcpy module: 2 candidates main debug: using memcpy module "memcpyaltivec" main debug: waiting for thread completion main debug: thread 33658368 (playlist) created at priority -47 (playlist/playlist.c:184) main debug: waiting for thread completion main debug: thread 33580544 (preparser) created at priority -47 (playlist/playlist.c:210) main debug: looking for interface module: 1 candidate main debug: using interface module "hotkeys" main debug: thread 34542080 (interface) created at priority -47 (interface/interface.c:198) main debug: looking for interface module: 3 candidates main debug: using interface module "macosx" main debug: thread 33667584 (manage) created at priority -47 (interface/interface.c:164) main debug: adding playlist item `10min.mpg' ( /Users/thymus/Desktop/10min.mpg ) main debug: creating new input thread main debug: waiting for thread completion main debug: thread 34849792 (input) created at priority 37 (input/input.c:261) main debug: creating statistics handler main debug: `/Users/thymus/Desktop/10min.mpg' gives access `' demux `' path `/Users/thymus/Desktop/10min.mpg' main debug: creating demux: access='' demux='' path='/Users/thymus/Desktop/10min.mpg' main debug: looking for access_demux module: 1 candidate macosx debug: input has changed, refreshing interface main debug: creating access '' path='/Users/thymus/Desktop/10min.mpg' main debug: looking for access2 module: 7 candidates vcd debug: trying .cue file: /Users/thymus/Desktop/10min.cue access_file debug: opening file `/Users/thymus/Desktop/10min.mpg' main debug: using access2 module "access_file" main debug: pre-buffering... main debug: received first data for our buffer main debug: pre-buffering done 1408981 bytes in 0s -
