I noticed the following in the dmesg output: [ 1094.573584] cx18-0 api: CX18_CPU_SET_VIDEO_RESOLUTION [ 1094.573659] cx18-0 api: mailbox error 20080003 for command CX18_CPU_SET_VIDEO_RESOLUTION I check and I am attempting to set the video resolution to 704x480. rmmod ivtv appears to have fixed this error. ivtv module really seems to interfere with cx18 quality. Video still skips in mythtv live tv playback and I see the following: [ 1818.130222] cx18-0 info: Start encoder stream encoder MPEG [ 1818.130225] cx18-0 api: CX18_CPU_SET_VIDEO_MUTE [ 1818.130303] cx18-0 api: CX18_CREATE_TASK [ 1818.130376] cx18-0 api: CX18_CPU_SET_CHANNEL_TYPE [ 1818.130455] cx18-0 api: CX18_CPU_SET_VER_CROP_LINE [ 1818.130532] cx18-0 api: CX18_CPU_SET_MISC_PARAMETERS [ 1818.130614] cx18-0 api: CX18_CPU_SET_MISC_PARAMETERS [ 1818.130693] cx18-0 api: CX18_CPU_SET_MISC_PARAMETERS [ 1818.130817] cx18-0 api: CX18_CPU_SET_MISC_PARAMETERS [ 1818.130891] cx18-0 api: CX18_CPU_SET_CAPTURE_LINE_NO [ 1818.130974] cx18-0 api: CX18_CPU_SET_INDEXTABLE [ 1818.131046] cx18-0 api: CX18_CPU_SET_VIDEO_IN [ 1818.131148] cx18-0 api: CX18_CPU_SET_VIDEO_RESOLUTION [ 1818.131251] cx18-0 api: CX18_CPU_SET_STREAM_OUTPUT_TYPE [ 1818.131335] cx18-0 api: CX18_CPU_SET_ASPECT_RATIO [ 1818.131446] cx18-0 api: CX18_CPU_SET_GOP_STRUCTURE [ 1818.131527] cx18-0 api: CX18_CPU_SET_AUDIO_PARAMETERS [ 1818.131620] cx18-0 api: CX18_CPU_SET_AUDIO_MUTE [ 1818.131713] cx18-0 api: CX18_CPU_SET_VIDEO_RATE [ 1818.131800] cx18-0 api: CX18_CPU_SET_FILTER_PARAM [ 1818.131880] cx18-0 api: CX18_CPU_SET_FILTER_PARAM [ 1818.131963] cx18-0 api: CX18_CPU_SET_FILTER_PARAM [ 1818.132047] cx18-0 api: CX18_CPU_SET_MEDIAN_CORING [ 1818.132151] cx18-0 api: CX18_CPU_SET_SPATIAL_FILTER_TYPE [ 1818.132263] cx18-0 api: CX18_CPU_SET_FILTER_PARAM [ 1818.132343] cx18-0 api: CX18_CPU_SET_FILTER_PARAM [ 1818.132425] cx18-0 api: CX18_CPU_SET_FILTER_PARAM [ 1818.132510] cx18-0 api: CX18_CPU_SET_SKIP_INPUT_FRAME [ 1818.132585] cx18-0 api: CX18_CPU_SET_VIDEO_MUTE [ 1818.132662] cx18-0 api: CX18_CPU_SET_MISC_PARAMETERS [ 1818.132750] cx18-0 api: CX18_CPU_DE_SET_MDL_ACK [ 1818.140037] cx18-0 api: CX18_CPU_CAPTURE_START [ 1871.070906] cx18-0 warning: Possibly falling behind: CPU self-ack'ed our incoming CPU to EPU mailbox (sequence no. 29955) [ 1871.070915] cx18-0 api: incoming: req 0x00007503 ack 0x00007503 cmd 0x02040001 err 0x00000000 args 0x00000000 0x00dc0c48 0x00000001 0x00000000 0x00000000 0x00000000 [ 1878.278370] cx18-0 warning: Possibly falling behind: CPU self-ack'ed our incoming CPU to EPU mailbox (sequence no. 30190) while processing > > > Did you notice if there was a lot of movement in the video at the time > > of the skips?
