I saw one with a Japanese tuner in a big T-Zone in Akihabara
Saturday (4th floor?).  I think it was around JPY 23,000.
I don't know what chip it had.

I bought an IO Data board, the GV-VCP/PCI.  It has no tuner,
just 2 composite and 1 S-video in, and 2 chips:  a Bt848KPF,
and a little Epson 28.6363C (the clock).  Really, that's all;
a few resistors and capacitors, and two chips.  It's pretty.
JPY 13,000.  Less to go wrong.

Warning:  problems and details follow...

It works in Japanese Win95, but the standard size seems to be 320x240.
The drivers and manual are in Japanese, so it's difficult for me.
I can't find any rating, but I think that most of the similar cards
could do 320x240 at 30fps.  On the other hand, NTSC is 700x525
at 30fps?  (262 lines interlaced at 60fps and 4:3 aspect ratio?
Or, does the vertical and horizontal blanks cut it down to 640x480?)
I hope to get about that performance writing directly to my display
board, but with a "double-size" overlay of 640x480 it looks like 15fps
and there are bad motion effects with the interlace.  I don't want
to watch TV at 320x240.

Soooo, hoping it's just a software limitation, I turn to Linux,
which is all I really want to use anyway.  But, I haven't quite
gotten it working yet.  The xtvscreen program displays grey lines
across the whole width of my monitor, in the vertical area where
the TV screen is, when I start capture (overlay).  It clears up
when I stop capture.

The xawtv program does a little better, keeping inside its own window,
but it's not getting the right source, and the source is *very* slow.
I'm inputting composite from a Japanese VCR.  If it's in video-1, I can
see it on "tuner" (but there is no tuner).  If it's in video-2, I can
see it on "video-1".  And, the screen (just 320x240) is split up into
about 8 rows that draw in parallel, like I'm getting 0.1fps.  (Is this
the temporal decimation feature?)  In xawtv, it's the same whether I
choose "ntsc-bcast-jp", "ntsc-cable-jp", or the other "ntsc"s.
Sometimes, after using xawtv for a few seconds, my keyboard and mouse
lock up, altho the TV screen keeps going (so I have to reset).

Does anyone have any hints or ideas about where the problems are?
Decoding the video?  Transferring to the display board?  No DMA?  I
noticed that BTTV uses PCI definitions for 2 ATI display boards, but
mine (PCI_DEVICE_ID_ATI_215CT222) is not one of them.  Is BTTV using the
XFree86 direct draw stuff instead?  Or, is that up to the TV
application?  /proc/pci reports an IRQ 255 for my display board--that's
bogus, right?  What area should I troubleshoot?

Or, has anyone used any of my same setup before?  Japanese NTSC
composite video?  ATI Mach64 215CT222?  IO Data GV-VCP/PCI?

I got the latest BTTV (0.5.13), the latest regular kernel (2.0.34),
the latest regular Lesstif (0.80), and the latest xawtv (2.15).
I'm using XFree86 3.2 (not 3.2A unfortunately) in 24 bit mode 800x600
and an ATI Mach64 PCI board with 2MB.  I've tried xawtv with the BTTV
version that came with it (modified 0.5.8) and the latest (0.5.13).
I've also tried compiling BTTV with and without -DUSE_PLL.  I added
the Mach64 address to the bttv module install at xawtv's suggestion,
since bttv didn't seem to find it automatically.  I'm running the apps
as root.  I've tried it with and without the tuner and msp3400 modules.

Please see the attached configuration note for more details.

Thanks in advance.
