Comment:

 I actually have initial code working for this task. It's still rather
 early days but it is capable of watching live tv in mythfrontend (and
 recording for subsequent replay).

 At this point there's no audio support (I have test code for audio that
 works but I haven't yet integrated it into myth), the system is also a
 little 'fragile' in that due to some initialization issues the ConvertX
 box needs to be reset before mythbackend is launched after a previous
 successful run. Both these issues are on my list to be fixed shortly.

 The changes made so far are 'modest' with some additional code in
 NuppelVideoRecorder, cardutil, videosource, jobqueue, channelbase and the
 configure script. There are also 5 (or so) additional files for the new
 functionality in the libs/libmythtv folder. The implementation uses V4L2
 as a model but it is NOT a reimplementation of V4L2 for Mac OS X, this
 code is really only enough at this point to get the GO7007 driver working.
 Other USB capture devices are feasible if the specs/docs are available but
 a PCI based card would not work with this approach due to needing kernel
 space support on Mac OS X to access the PCI bus.

 What's the best mechanism for attaching my work to this ticket now and as
 it progresses ? I can create a zip archive of the svn diffs and new files
 as one attachment and revise that each time, or I can attach the
 individual diffs and new files (though that would be a lot of attachments
 - probably nearly 15 or 20 given the headers etc.)

 Isaac - is it appropriate to reopen the ticket on this basis ?
