Hmmm.  I've never seen the edges so large that a normal TV's overscan 
didn't take care of them.  And, unless the DVD player is sending broken 
signals or the TV has been "adjusted" to prevent some 
overscanning--which is possible through many TV's service menus--normal 
overscan should take care of normal-sized edges.

My PVR-x50's /hav/e been getting larger and larger edges as they age (I 
get a nice 1" black bar at the top of my 67" TV because of one card), so 
maybe yours have just progressed farther than mine.  I don't know if 
there's a way to "tune" the image size on the cards (whether through 
Windows drivers or ivtv), but you might want to check with the ivtv list.

You're not, by any chance, using 704x480 resolution on the DVD, are 
you?  It's only meant for video with "clean" (i.e. "cut") edges.  You 
should use 720x480 for Myth's analog recordings.

(Yeah, I haven't yet tested out MythArchive.  I just got it--and the 
rest of Myth--compiled on my new HDTV system, and will play with it once 
I finish the roll-out of the new system to replace my production NTSC 
system.  (The plan was to do this before the season started--since I'm 
behind schedule, roll-out is much more challenging.)  Therefore, I fully 
admit this may be a stupid question if 704x480 isn't possible through 
MythArchive.)
