I have had the same problem... xine plays the files fine without the "stutter" but both livetv and recordings stutter like mad.
I am using a AMD Athlon XP 2800 overclocked as a 3200 pcHDTV2000 card with stock kernel DVB drivers Debian with kernel.org 2.6.13 kernel GeForce4 MX 440 8X AGP w/NVidia 7676 drivers using XVMC 512mb memory I never tried the 18 releases but it worked prior to 18 and has been broken for quite a few months now... I could view with xine and no one else had mentioned the problem so it got back burnered. Thanks for mentioning it so I could add my 'ME TOO!' :} On Mon, Oct 17, 2005 at 04:47:16PM -0600, Chris Dos wrote: > After talking with some people on the IRC, they suggested that I post my > message to the developer list since something has changed in the way the > DVB code handles buffers. > > Here is the post that I sent to the Users list: > > I have a HD-3000 card that I got working using the 18.1 Debian packages. > However, upgrading to SVN resulted in the frontend spewing "A/V diverged by > <dropped frames number here (usually around 3-5 frames)> frames, extending > frame to keep audio in sync" in > it's logs. > > I guess I need to layout my system and what I've found out so far. > > Relevant System Componets: > Debian Sid > AMD Sempron 64 1600+, overclocked to 2.0 ghz from 1.6 (lot of head room in > that > chip, I read someone getting 2.6 ghz out of it) > 512 MB PC2100 memory. > 7200 RPM IDE 120 GB Drive. > HD-3000 > PVR-350 > nVidia FX5200 DVI Card (Using XvMC, This outputs to my DLP HDTV) > ivtv-.4.0 > Kernel 2.6.13 using the DVB drivers for the HD-3000 > > It took me a good three weeks to the HD-3000 card to work properly.
