When the PiP window is on, bringing up the guide leads to visual problems. The guide has (when first brought up) a black bar horizontally, across the entire vertical portion of the screen matching the height of the PiP window. Moving around in the guide will clear this bar, but clearing the guide window many times leads to a temporarily dark screen. This dark screen clears in time (1-3 seconds). This also (about one time out of three) causes the same video output lockup that has to do with DMA errors. eg: {{{ ivtv0 warning: prep_user_dma: SG_length 336 page_count 336 still full? ivtv0-osd warning: ivtvfb_prep_dec_dma_to_device, Error with get_user_pages: 196608 bytes, 336 pages returned ivtv0-osd warning: Error: prep osd dma to device rc=-5 ivtv0-osd warning: DMA xfer from b73ecdf4 of 196608 bytes failed with (-5) offset = 0x2edec, total 388588 ivtv0 warning: DMA_TO: REG_DMAXFER 2 wait failed }}} John Harvey at one point submitted patches that resolved most of these dma errors, citing old ivtv firmware code that should not be used and was defunct. While I do not know any more specifics aside from this, I felt it would not hurt to mention it. Naturally I could be barking up the wrong tree, as I have no idea what I am doing. ;) " defect closed minor unknown mythtv head medium invalid 0
