I can also confirm this exact same issues on my MythTV Boxes as well.

RE: 1).
Quick channel changes on my Nova-T 500 DVB-T cause the front end to
crash. This is especially easy to do when changing from DVB-T (i.e.
TV3) to my Leadtek Winfast 2000XP (analog for Prime). This almost
always appears to cause the front-end to crash. It is repeatable, but
does not happen every time though.<br>
<br>
Additionally, changing channels on the Winfast can now lead to a full
system lockup, which did not occur before. i.e. there is no terminal,
no mouse movement, sound locked in repeated loop - true machine lockup,
only reset button works. Speed of the channel change in this second
case is not needed, so this may be (probably is) a different bug.<br>
<br>
RE: 2). I can confirm this happening as well. Speed of channel change
is not an issue for me. I could have been watching a channel (Live TV)
for a while, then change channel, and it fails. After this is appears
that the card is still 'in use' and entirely unavailable. Restarting
mythbackend, mythfrontend, or anything else I've tried does not free up
the card again. Rebooting the machine (power off) appears to be the
only solution - which makes me think it could be a firmware loading
issue, or something in the Nova-T driver itself.<br>
