I'm not sure what's wrong but the algorithms for calculating file sizes are broken in SWFUpload.

For example, I have the max upload size set to 400M via SWFUploadConfig. However, it's refusing files 400M or smaller. Perplexing. So I threw it into debug mode and in the debug output I found out it was somehow converting to 409600 bytes. That only comes out to 0.4M... no wonder my files were getting turned down.

Anyway, I got around this by setting it to an absurd 400000M. :) But does anyone know if this is a known bug, if there is a solution?

Kind of a tricky one, here. Look at /swfupload/_config.php, and you'll see how the file_size_limit is assigned to the JS object. SWFUpload wants you to use the unit "MB", not "M". Kind of silly, and should be idiot-proofed, but I'm sunsetting this module very soon in favor of a much more flexible and extensible plugin that hopefully won't give us this much grief.

Yes, I see a str_replace on line 10 which apparently is an attempt at idiot-proofing it.
