So, after much procrastination I bought myself a new Mac Mini and have set up my Mac Mini Media Center (M³C).

Some observations:

• While equinux' TubeStick has a cute name and is much cheaper than Elgato's EyeTV, the hardware didn't work well for me (only received 16 of about 30 DVB-T stations), and the software is just no comparison to EyeTV, both usability and features are much better in EyeTV.
• Snow Leopard completely messes up the Apple Remote, and full screen video display seems to lag sometimes. Hopefully they'll fix this.
• I got myself an Apple wireless desktop, which works, but the next time I think I'd rather go for a keyboard with integrated touchpad
• Getting my Toshiba TV to display the digital video over a digital connection without cutting of the screen or black borders was hard. I used to SwitchResX and all looks good with these exact settings. Create a new custom screen resolution and enter the values for horizontal and vertical in the text boxes. Then reboot and see if you can select the resolution (good luck!).

• Running my own webserver (i.e. this weblog) on the Mac works fine so far, I just have to understand launchd some day so that I can make the services start at boot time. Well, another day ;-)
