Great one!
Yes, reception from a device does work best when it's not sharing IRQs. :)
I recently (May/June) installed a Pixelview Play TV Pak (Bt878) into a
friend's new PIII 533E Biostar M6VBE+ motherboard system running
TurboLinux Workstation 6.0 and got it working with xawtv, kwintv and alevt
but could never get the audio side to work as well as unable to get the
digital camera to work (get a funny beating/flickering effect with no
picture when switch the source to composite video in). I feed the audio
out to the Mic or Line in of the mb's built-in ESS Solo-1 sound using
OSS/Linux. OSS works fine for everything else. Tested the Mic In and Line
In fine using other sources. Under Linux, the tv card initialises with
the volume at 0 it seems, so the Windows boot, initialise, shutdown, Linux
boot and initialise trick didn't work. No sound chip gets detected by
bttv as expected for a Pixelview.
The digital camera I believe works in one of the NTSC standards. The TV
standard here in New Zealand is PAL B/G though I've tried all the NTSC,
PAL and SECAM standards in Xawtv and kWinTV for the composite input to no
avail. Get the same funny beating signal with no picture. Do I need a
digital camera driver?
This Pixelview came with an FM radio tuner (separate antenna socket)
however without sound control I couldn't tell if the Linux radio tuner
apps were actually tuning it or not. :) It's the closest I have come to
any other radio hardware under Linux after WiNRADiO.
Haven't set up the remote I/R driver yet; got totally confused. ;-)
All the Play TV Pak items my friend has work fine from Windows 98A which
he never boots into anyway. :) So the hardware is fine.
I do get sound when my Pixelview Play TV (Bt848) fires up on me Mandrake
7.0 P233MMX system which also has a Pixelview ComboTV running as my VGA
card (Cirrus Logic 5446...). The TV tuner side use to work with an
early version of Itai Nahshon's xtv driver/app software before I upgraded
from Slackware to Mandrake. :) Must have another try at xtv, before going
back to work in 2 days time. :(
In my rc.local...
# LOAD the BTTV (BrookTree Bt848) driver modules
modprobe videodev
modprobe i2c verbose=1 scan=1 i2c_debug=0
modprobe tuner debug=1 type=5
modprobe bttv pll=1 radio=0 card=0
dmesg shows...

I love AleVT's date setting program (alevt-date) which I use to
syncronouse the local time here off the New Zealand Teletext clock on
Television 2 (and TV4), which I find very useful for real-time satellite
tracking (Predict Ver 2.1.1) and real-time astronomy (Xephem 3.2.3) as
well as good date/time stamping on emails of course.
The synched time also makes it a plus for the Wr-text program I wrote to
control a WiNRADiO comms receiver under Linux (the local and UTC date/time
both tick over their minutes pretty much in synch with WWV/WWVH on
shortwave or the time pips on a shortwave or Medium Wave station).
I plan to do meteor scatter radio monitoring and capturing meteors on
camera during meteor showers using Linux, so time stamping using
alevt-date, bttv, LiNRADiO all under Linux is going to be real cool! 8-)
I caught one Leonids meteor on a small security B&W 0.2 minimum lux
security camera two years ago then snap shot about 32 frames from VCR into
my Linux box using Itai's xtv app's screen capture and played the
sequenced images back using xanim *.gif after converting the .ppm files to
GIF.:) I see you can get 0.1 minimum lux composite security tv cameras
now.
In my XFree86 Autostart I put two commandline icons with...
/usr/local/bin/v4lctl setstation TV2
/usr/local/bin/alevt-date -oldbttv -set
Talk about Pixelview mad! 8-)
Ok, Space Mad too.
Cheers
Yuri
