-	There are a couple of different methods by which you can obtain and build the latest source code. Regardless of which route you take, all are performed from the command line within a console. The "basic" method is likely appropriate for most end users, though, in ~~some~~ cases, some users will have to use the slightly more "manually intensive" approach~~. This second approach~~ is effectively, for all intents and purposes, really just the same as the "basic" method, but ~~performing~~ the steps in a piecemeal fashion affords you the opportunity to tailor the source code or the "make"/build process as might be required in your particular situation. Again, before proceeding with ~~either approach~~, make sure you have installed all the prerequisite software listed above.	+	There are a couple of different methods by which you can obtain and build the latest source code.

	{{Note\|If you are using Ubuntu, you were previously very likely to run into a fatal compilation error within the v4l-dvb build process when it reaches the firedtv module. The reason for this is because Ubuntu had a bug in their packaging of the kernel headers. <b>This seems to be fixed</b> on a fully updated systtem (5 July 2011) This was a long standing issue, and one of the most frequently reported on the mailing list. <br>		{{Note\|If you are using Ubuntu, you were previously very likely to run into a fatal compilation error within the v4l-dvb build process when it reaches the firedtv module.

Suffice to say, more modern kernels (which I'd define as ~~~2.6.32 and ~~newer) are much more likely to work with the new media_build snapshots of the git tree. When the situation is more clear, please update this section accordingly~~.}}	+
