MythTV is often used just like this, with a single machine hooked up to a single television or monitor. However, it can also act as a media server for your network, making all the recorded shows, your music files and pictures available to any other machine on your network running the MythTV frontend. So, I was pleased to fine pre-built binaries of the MythTV frontend for OS X over on their wiki. I downloaded one from The Snider Pad and didn't have too much trouble getting it up and running. All I had to do was change the permissions in the MySQL configuration file on the MythTV box to allow non-localhost connections (set bind-address to 0.0.0.0 in /etc/mysql/my.cnf). After that, I could sit on my bed with the MacBook on its 802.11b connection and watch any of the recorded shows, or live TV even, remotely from my MythTV box.
Here's the main menu:
From there I'm only a couple of clicks from:
...wait, that's not the Daily Show...but I haven't seen this episode before...
So, Apple gave me a lemon upgrade; could I make some lemonade here?
I have a USB 2.0 PCI card in the PowerMac, but even back on Tiger, if I put it to sleep with a power-drawing device attached to that card, it wouldn't sleep properly and I'd have to power cycle it to get it back. So, I had gotten into the habit of keeping the USB cable for my SD card reader unplugged from the reader, but plugged into the PCI card: a pain, but better than trying to copy 7MP images over USB 1.1.
For backups, I used to have the computer wake itself up at 3am. I had SuperDuper scheduled to run at 3:05 and then put the computer back to sleep.
Since sleep wasn't going to work any more, I changed my backup schedule so that SuperDuper would run at 12:30am and then power the computer off. I then changed the scheduled wake up to be at 7am, a few minutes before my wife would get up and check to see whether or not our daughter's school was on a 2-hour delay.
The wakeup feature is accessible via the Schedule... button on the Energy Saver panel in System Preferences:
This did the trick nicely, because the scheduled wake up works even if the computer is off. So now, while I can't enjoy the power-saving benefits of sleep, I can at least keep my backup running out-of-hours and still avoid having to leave the PowerMac running 24x7.
I think that qualifies as lemonade, even if it's only Country Time and not the real stuff.
There is another discussion going on on Apple's forums about a possible fix for this sleep issue. Basically, it involves rolling back the drivers in the graphics update in a somewhat kludgy fashion. I think I will just wait until Apple releases a real fix though.
