Sound quality problems on audio cd-r

I have recently run into an annoying problem when burning songs to cd-r. I'm working on FLStudio4.5.2 and have produced some really decent tracks, but as soon as I burn these tracks to cd some unwanted noise gets added.
The best way to describe the noise is as a high-picthed metallic echo. It only seems to affect the high frequency sounds on the songs and it adds an additional even higher frequency echo on top of the existing sound. The low & mid frequency sounds don't seem to be affected that much.
I thought it might be the quality of cd-r I'm using but I've tried a couple of different ones and it's not solving the problem. The sound quality when I listen to the songs on pc is absolutely perfect and the quality doesn't deteriorate when I burn to cd, but the additional noise just makes listening to it impossible to enjoy.
Please can someone help???

My system:
2.8GHZ P4 processor
Audigy 2 ZS soundcard
512MB DDR400 RAM
40GB Harddrive
 
are you burning from FL? is latency a possible factor? are you mixing down to stereo .wav first?
 
Is everything 16bits/44.1kHz when you mix it down to the final .wav file????
(That is the CD-audio standard.)

If anything is doing conversions during the burn (like your burn software), you'll get artifacts.

Im not burning from FL. I export to wav and then usually do some final editing in Goldwave. Latency could be a factor, I'm pretty new at audio production and haven't quite come to grips with everything yet. I've also considered that maybe I just need to buy a proper cd-r drive like Plextor or Yamaha, because at the moment I have an LG which I've had for almost 2 years, so it can't be the best one around.
 
are you exporting the wav as 32-bit float on FL? if so, then your burning program is doing the dithering, and chances are that it sucks.

again, to emphisize what everyone else has said, you need to make your wav 16bits/44.1kHz stereo for burning to a cd-r.

I think I might have found the problem, although I haven't tried burning another cd yet.
The Audigy 2 ZS, I discovered last night, only has settings for 96kHz or 48kHz and at the moment it's set at 48kHz, so I am assuming that FLStudio will also export to wav at 48kHz. Such a small difference from 44.1kHz though - could that really be the issue?
 
The difference between 44.1 and 44.2 is "huge" -

The difference between 44.1 and 48 is "complete failure."

Those tracks must be 44.1kHz 16-bit before the burn.

Could you recommend a good sample rate converter?
 
I'm not crazy about any of them, but the r8brain really is a pretty good software solution.
