I've done some DVB-T work, and I know the Novas work very well with the
LinuxTV drivers... If you have the model number for the Aver card, ask
about it on linux-dvb at linuxtv.org before buying.

'Teletext' support is pretty meaningless with the cheap DVB-T cards -
all they do is shift a raw MPEG2 Transport Stream into userspace, where
your applications will need to decode / process it.

These streams include audio, video, digital and analogue-encoded
teletext, subtitles, etc. - basically whatever the broadcaster has
chosen to supply.

There is no solution right now for viewing 'digital teletext' (MHP /
MHEG5) interactively from a DVB card on Linux, and the analogue stuff is
pretty Heath-Robinson unless you're using one of the much more expensive
DVB cards with onboard MPEG2 decoder that can do the VBI re-insertion
itself.

Cheers,
Gavin.
