While researching media center PC's, I needed DVB-T channel and stream IDs for Luxembourg. While channel info is readily available, the details of the MPEG-2 Transport Streams are not... and you need those for manual tuning.
I'm spending most of my free time hacking around on various linux projects. This is mostly about running Linux/PPC on my PowerMac 7500 and on my TiBook.
A quick selection of Macintosh-related Linux links:
A driver for the PlanB video input of the PowerMac 7x00/8x00 series
I would like to watch TV under Linux as well ;-)
Starting with version 2.2.8, PlanB is part of the official Linux kernel sources. However, the version in the kernel sources needs some overhaul. I suggest applying patches.
The patches are updated for the most recent kernel versions (2.4.16 kernel.org and 2.4.17-pre1 (benh's tree) ).
Later 2.4 kernels should not need patches. 2.6 kernels are curently unsupported due to lack of time to work on those.
Some locally mirrored software and other special stuff. Use at your own risk!
This is not kept up-to-date regularly, and serves mostly my own purpose.
