Visit the MythTV on Slackware PVR350 HowTo thread for more info. He has some great tips on which IVTV drivers he has had the most success getting OSD/menu support through the PVR350’s tv out.
Good job homebrew!
xar256 also linked to a fedora core2 mythtv how to (fedora is redhat’s “free” iso distro as opposed to their retail server/workstation products) also of note the Wilsonnet mythtv guide. These will be added to the link directory.
I’ve mirrored the MythTV on Slackware PVR350 HowTo here.
