10.6.3 - still error 36 file copy errors

Question

After getting a new mac with 10.6 I started having problems copying files, namely that copying aborts with error 36 quite frequently. I never had such problems on my old powermac with 10.3.9. After some reading here, I discovered this was a known 10.6 problem when copying to windows formatted disks.
Recently I let my mac upgrade itself to 10.6.3. One of the listed fixes was for file copies to windows servers. Unfortunately, I'm still getting error 36's. I have 2 ways that I transfer files which yield lots of error 36's :
First is with USB thumb drives formatted FAT32, for backup and taking files back and forth from home/office & pc/mac. I haven't yet experienced a problem with this in 10.6.3, but really I also haven't transferred many files this way yet, so can't say for sure whether the issue is fixed here or not.
Second way is uploading completed projects (mostly pdf's) to our corporate site via internet, doing a "connect to server" with afp://mycompanysite.com. I have no idea what server/software they are running with that, but I still get consistent error 36's when uploading files to it. If I make that afp connection with my ancient 10.3.9 powermac, I can transfer files all day without any errors, so...
obviously Apple still hasn't quite fixed the file transfer problem!!
Help, Apple, Help!!!!!

Thank you for your reply, Charles.
1. I thought that this thread was about Finder in 10.6.3 generating Error -36 errors when trying to copy files to an external drive, which is what I wrote about.
Yeah, but it appears that the OP had a different problem.
2. i know that I shouldn't have to force-eject DVD-RAMs; I mentioned that precisely because it is unusual. I was hoping that by raising all the problems that I noticed, maybe someone would recognize something that would lead to a solution.
If you have to force-eject discs, odds are that you have a problem directly related to that device.
3. Hardware problem is unlikely. The drive works fine in all respects with my older (17") iMac running OSX 10.4.11; the drive works fine with the new iMac running OSX 10.6.3, when copying any size file to or from a DVD-R or DVD-RW disk; the drive also works fine with the new iMac when copying small files (less than 1.4MB or so) to a DVD-RAM; the drive also works fine when copying any size file FROM a DVD-RAM. The error occurs ONLY when copying a file larger than about 1.4MB to a DVD-RAM. To me, the key point is that it works perfectly with 10.4.11, but not with 10.6.3. The only other difference is that with the old iMac I used the Firewire 400 port, and the new one is 800 (so I use a converter cable); but i don't think that would explain why there is no problem with DVD-R and DVD-RW, nor with small files, nor with copying from the drive to the iMac.
It would appear that there's a software problem somewhere which relates directly to that device. You need to check the drivers.
4. The mechanism is TSSTcorp CDDVDW SH - 5203N, firmware version LA00 (which is the latest). I have already contacted LaCie about this as well. They don't know why it doesn't work, either. But, on the other hand, they admitted that they do not know of anyone who does have 10.6.3 and IS able to copy larger files to a DVD-RAM. Do you?
Nope. Most people around here use DVD-Rs or DVD-RWs, not DVD-RAMs. I've not heard of that particular model DVD-RAM.
Thank you.
