Ivtv has some new messages in dmesg though: saa7115: decoder disable output saa7115: decoder set input (8) saa7115: now setting S-Video input ivtv: Setting audio matrix to input 1, output 1 saa7115: decoder enable output saa7115: decoder disable output saa7115: decoder enable output ivtv: DEC: REG_ENCSG1LEN wait failed ivtv: DMA Registers State: xfer: 0x00000002, state: 0x00000001 dec_addr: 0x00000000 enc_addr: 0x44360060 control: 0x00000003 ivtv: DMA DEC Buffers: 0x00000000:0x00000000:0x00000000 ivtv: DMA ENC Buffers: 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 ivtv: ENC: REG_DMAXFER wait failed ivtv: DMA Registers State: xfer: 0x00000002, state: 0x00000001 dec_addr: 0x00000000 enc_addr: 0x44360060 control: 0x00000003 ivtv: DMA DEC Buffers: 0x00000000:0x00000000:0x00000000 ivtv: DMA ENC Buffers: 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 ivtv: ENC: User stopped capture. ivtv: ENC: DMA still Pending while stoping capture! ivtv: ENC: REG_DMASTATUS2 wait failed ivtv: DMA Registers State: xfer: 0x00000002, state: 0x00000001 dec_addr: 0x00000000 enc_addr: 0x44360060 control: 0x00000003 ivtv: DMA DEC Buffers: 0x00000000:0x00000000:0x00000000 ivtv: DMA ENC Buffers: 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 0x00000000:0x00000000:0x00000000 Thanks, Dave --=20 David Muench - davemuench@gmail.com Jabber ID: dave@jabber.wasteland.org
