Hmmm, that's interesting from a number of perspectives....

Are you using alsa or oss?  I've previously noticed that when I switch from 
oss to alsa, the mixer choices change.  After a recent kernel compile after 
which I ended back up with the default kernel oss drivers and kudzu redected 
the card, I ended up with my current mixer as mentioned in the previous 
email, since reinstalling/setting up alsa again, the mixer strangely enough 
hasn't changed to the one I've come to expect from alsa.

Everything otherwise works fine though.

Not currently, however that is in the plan. Not sure if I'll need to replace 
my amp, as AFAIK, it will only play non digital audio via the analog inputs 
on the amp. I haven't tried using a coax only cable. Although that would sure 
simplify cabling for me.  I do have the digital I/O card for my SBLive which 
has an spdif in and out so I may just give that a try when I have a few spare 
minutes.

That's about what I expected

I used to have an avermedia card in my machine however it also wasn't btaudio 
capable, maybe you have one of the aver cards with the sony chipset.

Seems to me that is the mixer for alsa.

Good, that's expected.

Yes, that I noticed, especially when playing cd's.

Totally!!! I have about 6 or 8 tuners In order of visual quality, from best 
to worst, in my experience:

PVR-250 looks amazing! I plan to get a second one soon.
ATI TV Wonder - depending on settings can look pretty crappy, normally looks 
pretty good, although not as good as the pvr-250.
Aim's labs Videohighway/Vxtreme - decent video generally
WINTV Pci (similar to the wintvgo) - iffy, sometimes looks good and sometimes 
bad, both in linux and windows
AVER TvPhone - looks crappy period, I've seen postings about the amount of 
noise that their connectors introduce in the video

 
> I need the playback button on lGain checked also.
Hmm, yes that sounds right, I wish I had kept notes the last time I went 
through this.

> Yeah, I'm still tinkering a bit.
Heh, maybe you post any notes you come up with.

Well, that's to the good of all, I'm surprised more people haven't posted 
about this since the Creative cards seem to be in high use judging by posts 
on this list. Mind you dual tuner use seems much less common....

Might I suggest dumping that card and getting a TV Wonder (not the VE), if 
for nothing else than the better video quality.

Bummer dude.
