I don't like the above lines, I think we got the system confusing the card's inputs. (aerial, s-video and composite)

>> DEVLINKS=/dev/analog1250 /dev/v4l/by-path/pci-0000:02:00.0-video-index0
>> DEVLINKS=/dev/digital1250
>> DEVLINKS=/dev/digitalKworld

It says the links have been created. Please verify with "ls"

>> DEVLINKS=/dev/v4l/by-path/pci-0000:04:00.0-video-index0
>> I'm going to reboot now and see how it looks.

Yes, we can call these "teething problems" :). And the time difference doesn't help, either.

That is not good, I'm afraid. We are using a subsystem of the video0 card.

The only devices that will be

I've rephrased the symlinks to create the digital devices under /dev/dvb. Also, I found a different approach for the pvr150 in the archives.

Please try the rules below, but feel free to change the symlinks to your liking before you do.

# Analog side of Hauppauge WinTV-HVR-1250
SUBSYSTEM=="video4linux",ATTRS{vendor}=="0x14f1",ATTRS{device}=="0x8852",SYMLINK+="an1250",GROUP="video"
# Digital side of  Hauppauge WinTV-HVR-1250                                                
SUBSYSTEM=="dvb",ATTRS{vendor}=="0x14f1",ATTRS{device}=="0x8852",SYMLINK+="dvb/dig1250",GROUP="video"
# Analog Kworld PC150
SUBSYSTEM=="video4linux",ATTRS{vendor}=="0x1131",ATTRS{device}=="0x1733",SYMLINK+="AnKW150",GROUP="video"
# Digital Kworld PC150
SUBSYSTEM=="dvb",ATTRS{vendor}=="0x1131",ATTRS{device}=="0x7133",SYMLINK+="dvb/DigKW150",GROUP="video"
# Hauppauge computer works Inc. WinTV PVR 150
# Adapted from http://www.mythtv.org/pipermail/mythtv-users/2008-March/217517.html
KERNEL=="video[0-9]", ATTR{name}=="ivtv[0-1] encoder MPG", ATTRS{subsystem_device}=="0x8801",SYMLINK+="videopvr150",GROUP="video"

After rebooting to get rid of the stale symlinks, verify the new have been created (ls -lah is your friend) and I suppose the real test will be to stop any myth process (backends, frontends) and try mythtv-setup.
