lets try and correct them, in addition to pointing them out.

alsa is better for non pvr-250 and non btaudio installations only, 
right?  in other words, when you need to use the sound card in full 
duplex mode, and perhaps in some special cases where the kernel audio 
has problems (like VIA M-10000)?

lirc on the pvr uses the i2c interface, and that's the reason for 
possibly needing to recompile, right?  but if you had a recent kernel, 
then it might not be necessary.  the i2c and the v4l(2) stuff are whats 
important for the kernl, is this correct?

well, this is certainly not always the case.  if i drop the bitrate 
below an average of about 5Mbps, i get choppy audio and video.  now that 
i've patch mplayer, i should test to see if it is just myth, or the 
actual recording thats the problem.

this is certainly the right way to do this.

normally, this is how this starts.  someome takes something and does a 
good job of it, then it can get submitted and hopefully included.  by 
and large, these howtos start out as 'this is what i had to do' and 
grows from there.
