The drivers may already be in the OS.
A quick Google search for "Digivox ATSC USB TV linux" points to this
page and the device may be the one listed under the Validated table as
EM2820_BOARD_MSI_VOX_USB_2...
http://linuxtv.org/wiki/index.php/Em28xx_devices
On my RHEL 6 system for example, I did a quick "locate em28" in a
shell. Looks like em28xx is there, and the card appears to be listed
as #5 here...
/usr/share/doc/kernel-doc-2.6.32/Documentation/video4linux/CARDLIST.em28xx
Taking a step back, I've been burned enough in the past that I now
tend to figure out which devices work great on Linux before buying
them. Less headaches, rocket science, and disappointment that way! I
really hope it "just works" for you with minimal fuss!

Actually there are three drivers related to this group of devices,
em28xx.ko , em28xx-alsa.ko , em28xx-dvb.ko
Also someone reported your MSI device working under Debian
Lenny (w/o details).
http://linuxtv.org/wiki/index.php/Em28xx_devices (needs your feedback)
The site says the em28xx parts don't need firmware, tho' the tuner might.

Dave is correct about doing a selection selection of hardware based on
Linux drivers. However over the years, making my Hauppage PCTV work has
gone from a weekend science project to an out-of-the-box install -and-go
experience. ~2.5 year ago no USB vid devices were supported according
to the V4L developers; today there is a long list. Linux lags a bit on
these
end-user hardware devices.
