Hi there Bernhard, Thanks for responding.

I'm using mjpegtools 1.6.2, driver-zoran 0.9.4, and the i2c stuff in the 2.4.27 kernel (kernel.org). I haven't tried the cvs versions mjpegtools or driver-zoran, but I have read through the latest driver-zoran sources via the CVS and I can see that they will not solve my problems. The problems I was seeing seem to be only in the driver module - I think lavrec and lavplay are working fine. xawtv works with the current driver on my machine.

I believe that there is a hardware conflict with the buz cards on all but the beige G3 powermacs - apparantly the scsi controller on the boards causes a problem. I read somewhere that you can remove the scsi chip from the card to get it to work :P. I'm guessing you won't want to do that (I wouldn't :)). Anyway, since my last message I've made some further progress with the driver-zoran sources and have had some very successful playback and record sessions now uysing lavrec/lavplay with decimation = 2 or 4. Decimation = 1 crashes. BTW - the crashes are silent - no incriminating messages on the console or in messages - the machine just stops!. I'll see if I can instrument the driver to get some debugging output for this that can be discussed. Colours are fine - the problem I reported in my last email was with mplayer, not the file produced by lavrec. The avi's I've captured play fine in VLC and lavplay through the buz. There are two problems with driver-zoran 0.9.4 that I have worked around. These are: - zoran_driver.c did not include linux/vmalloc.h. vmalloc is a static inline defined in that header (in 2.4.27 at least), and without it the module still builds but cannot be loaded, complaining that the vmalloc symbol is missing (which it is). - The stat_com and fragment table buffers. The zr36057 reads these from system memory, and expects them to be in little endian format (which they are not on PPC!). The result of this is that when compression starts, the compressed JPEG stream is written who-knows-where and the machine locks up very quickly! Anyway, I'll download the latest mjpegtools and driver-zoran sources from cvs and have a go. I'll submit a patch against CVS for the issues I addressed above to the devel list after I try them out. I'll also try to provide more information on decimation=1.
