Hi Hans, I grepped the ivtv messages out of /var/log/dmesg and here they are: ivtv: Start initialization, version 1.1.0 ivtv0: Initializing card #0 ivtv0: Autodetected Hauppauge card (cx23416 based) ivtv0: Unreasonably low latency timer, setting to 64 (was 32) ivtv0: Autodetected Hauppauge WinTV PVR-150 tuner 0-0061: chip found @ 0xc2 (ivtv i2c driver #0) cx25840 0-0044: cx25843-24 found @ 0x88 (ivtv i2c driver #0) wm8775 0-001b: chip found @ 0x36 (ivtv i2c driver #0) ivtv0: Registered device video0 for encoder MPEG (32 MB) ivtv0: Registered device video32 for encoder YUV (2 MB) ivtv0: Registered device vbi0 for encoder VBI (8 MB) ivtv0: Registered device video24 for encoder PCM audio (1 MB) ivtv0: Initialized card #0: Hauppauge WinTV PVR-150 ivtv1: Initializing card #1 ivtv1: Autodetected Hauppauge card (cx23416 based) ivtv1: Unreasonably low latency timer, setting to 64 (was 32) tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #1) ivtv1: Autodetected Hauppauge WinTV PVR-250 saa7115 1-0021: saa7115 found (1f7115d0e100000) @ 0x42 (ivtv i2c driver #1) msp3400 1-0040: MSP4448G-A2 found @ 0x80 (ivtv i2c driver #1) ivtv1: Registered device video1 for encoder MPEG (32 MB) ivtv1: Registered device video33 for encoder YUV (2 MB) ivtv1: Registered device vbi1 for encoder VBI (8 MB) ivtv1: Registered device video25 for encoder PCM audio (1 MB) ivtv1: Initialized card #1: Hauppauge WinTV PVR-250 ivtv: End initialization Thanks Yan _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
