I'm guessing that this has something to do with "recording profiles".
Here are the database entries for my old (1214) profiles :
(1,'Default','RTjpeg','MP3',1),
(2,'Live TV','RTjpeg','MP3',1),
(3,'High Quality','RTjpeg','MP3',1),
(4,'Low Quality','RTjpeg','MP3',1),
(5,'Default','MPEG-2 Hardware Encoder','MPEG-2 Hardware Encoder',2),
(6,'Live TV','MPEG-2 Hardware Encoder','MPEG-2 Hardware Encoder',2),
(7,'High Quality','MPEG-2 Hardware Encoder','MPEG-2 Hardware Encoder',2),
(8,'Low Quality','MPEG-2 Hardware Encoder','MPEG-2 Hardware Encoder',2),
(9-20,'Default',NULL,NULL,3),
(21,'RTjpeg/MPEG4','MPEG-4','MP3',6),
(22,'MPEG2','RTjpeg','MP3',6),
(23,'Default',NULL,NULL,8),
(24,'Live TV',NULL,NULL,8),
(25,'High Quality',NULL,NULL,8),
(26,'Low Quality',NULL,NULL,8),
(27,'High Quality','RTjpeg','MP3',6),
(28,'Medium Quality','RTjpeg','MP3',6),
(29,'Low Quality','RTjpeg','MP3',6),
(30-49,'Default',NULL,NULL,10),

And here are the database entries for my new (1244) profiles :
(1-53,'Default',NULL,NULL,1),

Now that I look, the 'description' and 'profile group' entries obviously
change between profiles, but what I believe is key here are the
'videocodec' and 'audiocodec' values.  For all of the new/1244 profiles,
they're "NULL", and for at least profile groups 1 and 2 in the old/1214
profiles, there were sensible values there.  Now that I look again, I'm
still not seeing "48000" or "32000" in either, though I suspect that the
latter is some sort of default setting of the card.

I believe the problem here is my setup, though perhaps nuvexport could
be a little more robust about handling erroneous input.  Right now I'm
more wondering 2 things:
1 - Can I slip some values in "under the covers" so nuvexport can make
sense of what it sees when it looks at my recordings?
2 - Should I be changing these "default" values to something a little
better?  For instance, next time I try playing 32000 Hz sampled audio on
my fixed-48000 Hz sampling AC97 audio system, will the annoying audible
artifacts be back, again.
3 - (cheating) How can I reconcile #1 and #2?  Assuming I do #1 and make
nuvexport start working, as soon as I do #2 to make future recordings
better, will nuvexport quit working on current recordings?

Thanks,
