Hi Hans, This is an older topic, but I wanted to send an update, it could be useful for other users. I was not able to rid off these messages with the latest MythTv from SVN. > > ivtv0: All encoder VBI stream buffers are full. Dropping data. > > ivtv0: All encoder MPEG stream buffers are full. Dropping data. A guy on the MythTv list told me to try this: options ivtv tuner=55 enc_mpg_buffers=16 enc_vbi_buffers=8 I did not receive any errors since then (2 days long). Can these options some negatively affect my recordings?
