Are Kodak CDR's reliable and at least fairly standard CDR's? I ask because I may buy 400 of them. Anyone know what "infoguard protection system" is? The auction says they come with it. Kinda sounds like some kind of anti bootleg thing or something.

They are fine.

The gold ones are better, but very hard to find.

The silver and gold ones are good. Infoguard is a technology they claim extends the life of data recorded on their media.

I purchased 200 of them and almost used them all and have yet to find a bad one.
You can read more about infoguard HERE (http://palimpsest.stanford.edu/bytopic/electronic-records/electronic-storage-media/kodakpho.html).

Sweet. Thanks for the info.

Dont think Kodak makes CDRs anymore, so they might be a year or two old. I only had a foil issue with 1 cdr ever with Kodak silver.
Good luck
