	Don't get me wrong, I know the difference, and I was not trying to 
imply that I was getting HDTV on a non HDTV. :)
	That being said, an HDTV video file (even at the common lower xvid 
resolution) is still *FAR* better than regular TV. :D
	The funny thing is I use to download SVCD video files and burn those to 
CD and watch them. Now that my DVD player has native "divx" capability, 
I only download the xvid files. Besides, the SVCD versions quickly 
disappeared once the first "divx" capable DVD players hit the market 
back in early y2k.
	Unfortunately I am not overly happy with the performance of my "divx" 
capable DVD player. As such I am planning on deploying a playback only 
mythtv box. I have no incoming TV signal to speak of so I don't need a 
rig capable of recording, only playback. I do still need ripping 
capability though.
