Hi Nick.  I did not get around to writing the little 350 HOWTO last night.  I 
didn't leave work until very late and was exhausted (damn those hard to find 
bugs!)  Anyway, it seems that you got the X driver for the 350 set up, right?  
If so, then use these settings in your Xorg.conf file:

Section "Monitor"
   Identifier "Sony TV"
   HorizSync 30-50
   VertRefresh 60
   Mode "720x480"
     DotClock 34.564
     HTimings 720 752 840 928
     VTimings 480 484 488 504
     Flags "-HSync" "-VSync"
Section "Device"
   Identifier "ivtv"
   Driver "ivtvdev"
   Option "fbdev" "/dev/fb1"
   BusID "01:0x09:0"
Section "Screen"
   Identifier "Screen TV ivtv"
   Device "ivtv"
   Monitor "Sony TV"
   DefaultDepth 24
   DefaultFbBpp 32
   SubSection "Display"
     Depth 24
     FbBpp 32
     Modes "720x480"
     ViewPort 0 0

Of course, ensure you have the right "fbdev" and "BusID" options in there for 
your system.

Sounds like you've already gotten pretty far with it anyway, but these are the 
proper settings (for NTSC anyway), so I just put them out there so you can 

I will still write the HOWTO soon.
