I've had it working with,, and 2.6.20 kernels. I've not 
tried it with 2.6.19 (without a fourth-digit revision number), though. A few 

1) On my system, I get just one /dev/video* device for the HD3000. I'm not
   sure why you're getting two, unless you've got two cards. It's possible
   that's related to your problem, but that's a wild guess. Try this command
   to check what each of the devices is:
   udevinfo -a -p $(udevinfo -q path -n /dev/video0)
   Replace "video0" with "video1" for the second device. This will give you
   information on the driver and device associated with each device file.

2) What MythTV backend setup options are you using? In the mythtv-setup
   program, you should select "DVB DTV Capture Card" as the "Card Type" in
   the "Capture Cards" area. From your mention of the "Analog Options", I
   suspect you're already doing this, but I'm not 100% positive of that, so
   I thought I'd mention it.

3) I've found that it works best if you create two Zap2It lineups, one for
   digital channels and one for analog channels. Create two video sources in
   mythtv-setup, one for each of these lineups. This will let you keep
   channels straight, particularly if you've got an NTSC-only card in addition
   to the HD3000.

4) You've got to assign video sources to both the digital and the analog
   tuners in the "Input Connections" part of mythtv-setup.

5) MythTV seems to favor the digital stations if you tune directly in live TV,
   at least unless you take steps to favor analog stations by playing with the
   input priorities. Check your program guide and schedule a recording on an
   analog station to force an NTSC recording.
