Re: mythtv daemon shutdown
This one time, at band camp, garrone said: I am trying to get mythtv to do its automatic shutdown/wakeup for recording of favorite television program. In the debian multimedia package, it's backend daemon is set to run with user (called mythtv) privileges. Debian shutdown refuses to shutdown if the user is not the superuser. Is there anyway to allow the mythtv backend to bring the system down without giving it root privilege? It can be set up to run anything to shutdown. /etc/sudoers: mythtv ALL=(ALL) NOPASSWD:/sbin/shutdown and then write a wrapper script that calls 'sudo shutdown -h now' (or just use that as the shutdown command). -- - | ,''`.Stephen Gran | | : :' :[EMAIL PROTECTED] | | `. `'Debian user, admin, and developer | |`- http://www.debian.org | - signature.asc Description: Digital signature

Isaac, is it a bad solution to replace them permanently in RingBuffer.cpp?
Yes. That patch isn't correct, and I'm not going to stop using standard
functionality just because it's broken on one little-used platform. I'm
fairly sure people are using native 64-bit stuff elsewhere, so it's just
seems like Debian's behind as usual.
i upgraded the patch for mythtv 0.17 anyway, as i don't want to wait for
debian/pure64 to fix the glibc.
here it is, for all the people that like to run mythtv 0.17 on
debian/unstable pure64.

Re: mythtv
I read your post about MythTV . Most of the popular new PVR cards sold for Windows XP MC are based on Connexant's Blackbird design, which hasn't had drivers for Linux or Myth. We have been working on these drivers and released an alpha version at http://plutohome.com. Pluto even has a self-booting kick-start CD that will automatically install configure everything for you, including a ready-to-go Myth system. It's the fastest and easiest way to get a MythTV PVR up and running, and also installs Xine, Asterisk and our own software to give you the most advanced media entertainment, home automation, security, telecom computing system, controllable with your Symbian Bluetooth mobile phone, as well as PDA's and Webpads. We're working hard to harden the drivers as quickly as possible and would like as much feedback as possible. These 2nd generation Blackbird cards are lower in price and offer better picture quality than the current models supported in IVTV, so be sure to check them out. visit: plutohome.com, click 'support', 'support site', and choose CX88 Blackbird Drivers from the projects menu Loredana Lacatus Pluto ..

It compiles nicely with some minor warnings with gcc-3.4. I have been able to compile everything but as everyone knows a clean compile does not mean that it will run perfectly. Anyway the problem is with mythtv because the ivtv driver works fine with xine, and mplayer. I'm not sure if mythtv is 64 bit ready or not. I was wondering if there were any 64 bit patches running around for mythtv, or something else that I'm missing? This is the only show stopper to make the jump to 64 bit. I guess I could stop watching TV, and use my computer for something productive ;-)). Note the 0.1.9 was the last stable release, but the bleeding edge releases have amd64 support directly.
