My limited experience with TV tuners in Linux has told me not to look at
the make and model of the tuner so much as the chipset. Find out what the
chipset is and Google that and UbuntuStudio. Note: I currently do not have
a tuner, but have owned several in the past. There are a few chipsets that
are used by many manufacturers and the same help would apply for the
various makes as long as they share the same chip.
