Exactly.

OK. Can you check the JPEG frame output? I'm assuming that you're
capturing to AVI for the Buz as well. OK, so, open the resulting AVI
file in hexedit. It starts with a RIFF header ("RIFF....AVI "; the dots
indicate the chunk length, just ignore them), then all file headers
("LIST....hdrl") and then a whole bunch of crack. The total header,
including RIFF header, will be 2048 bytes, so just scroll down to
position 0x800. There, you will see the movie header (LIST....movi) and
then the video/audio data. The first should be a video frame (00db....).
Now, look at the data directly after the four dots. There should be some
JPEG chunks. They look like 0xff, then a tag, then 0x00 and then the
length (1 byte) and then the chunk data. Look for a tag '0xe0' or
'0xe1', so look for something like 0xff, followed by either 0xe0 or 0xe1
and then 0x00.The length should be 16 bytes (0x10), and the data should
start with AVI1. If it does that, all's right. Else, it's still buggy.
Can you try to check that?

How cool, it captures one frame and then errors out. There should be
exactly one frame in the resulting AVI file, can you check the same as
for the buz, i.e. if the APP0 tag is written correctly now?
I'll look at what the win32 driver does here, I'm pretty much clueless
as for why it would error out because of this change. I must have made
some obvious typo somewhere. I'll try the DC30 myself as well (I only
test on the DC10+, usually).
Thanks for testing. :).
