A few days ago, I reported this issue resolved with the latest Myth SVN. Unfortunately, I was wrong. However, the problem appears to be minimized, now. It is hard to recreate. It seems to me, that Myth is not doing fadeouts when the guide is up.. or that it usually doesn't. When it does, the below happens: ivtv warning: prep_user_dma: SG_length 336 page_count 336 still full? ivtv-osd warning: ivtvfb_prep_dec_dma_to_device, Error with get_user_pages: 458752 bytes, 336 pages returned ivtv-osd warning: Error: prep osd dma to device rc=-5 ivtv-osd warning: DMA xfer from b746d434 of 458752 bytes failed with (-5) offset = 0xca42c, total 1287212 ivtv warning: prep_user_dma: SG_length 336 page_count 336 still full? ivtv-osd warning: ivtvfb_prep_dec_dma_to_device, Error with get_user_pages: 458752 bytes, 336 pages returned ivtv-osd warning: Error: prep osd dma to device rc=-5 ivtv-osd warning: DMA xfer from b746d434 of 458752 bytes failed with (-5) offset = 0xca42c, total 1287212 ivtv warning: DMA_TO: REG_DMAXFER 2 wait failed On Wed, 28 Sep 2005 07:46:25 +0100 "John Harvey" <[EMAIL PROTECTED]> wrote: > There are fixes in latest myth branches after 0.18.1 (ie 0.18.2 ) and > the main branches that will probably fix both of these problems. > > John > > > -----Original Message----- > > From: [EMAIL PROTECTED] [mailto:ivtv-devel- > > [EMAIL PROTECTED] On Behalf Of Brad Barnett > > Sent: 28 September 2005 01:06 > > To: [email protected] > > Subject: [ivtv-devel] pvr-350 bug in ivtv-0.3.8 with Debian's MythTV > > 0.18.1 > > > > > > > > Is this message getting though?
