I wouldn't really agree with that - I'm using two PCI NOVA-Ts. If
you're in an area where freeview reception is marginal then you *may*
find that some DVB cards perform better than others. However if your
freeview signal strength is reasonable then any DVB card should
perform as well as a freeview box. In fact if you're connecting your
myth box to the analog output of a freeview box then the
digital-to-analog-to-digital conversion will degrade the signal
significantly below that of the DVB card.
Where a dedicated freeview box might out-perform a mythtv box is in
playback. I'm using
the S-Video output of an NVidia 5200 connected to a Plain-old-CRT and
I find that for some sports (eg soccer) the playback is noticeably
worse than both the analog input direct to my TV and via my btvision
freeview box. I believe that this is something to do with a 50Hz/60Hz
incompatibility between the broadcast and the NVidea S-Video output?
Scrolling text can also look a bit jerky For every other type of
programme I'd say the mythtv output looks as good as that from the
freeview box but either way it's not a reception issue.
If I were you I'd look at the some of the Freeview Quality Indicator
websites for your area and, if you're well served then I'd seriously
recommend a DVB card over a freeview box.
You could also ask on this list if anyone in your area can recommend
Apart from the ease of channel changing, advantages of a DVB card are.
1) No need to worry whether the freeview box is turned on.
2) No loss of quality (due to digital-analog-digital conversion)
3) Ability to record multiple channels simultaneously from a single tuner
4) Ability to easily add tuners.
5) Access to the DVB EIT (programme listing) data.
