It's possible you may need to update your copy of Nero, but the more likely explanation is that your DVD media isn't good enough to burn at 16X. Yes, you can download firmware patches that let you override the media write power table profiles, but I STRONGLY DON'T RECOMMEND this, no matter how many times you hear a "friend" having done it. DVD-/+R is pretty fragile stuff, really. I've done media surface scans on marginal brands of media as well as high quality Taiyo Yuden stuff, and doing a proper burn is essential if you wish to actually read data from your DVDs a few months or a year from now. You'd be amazed at how high the error rates are with marginal brands of DVD media, especially when burned at maximum speed. The higher the error rate, the slower the media will readback, and the shorter its expected lifespan. You may wish to avoid burning faster than the rate at which the burner switches to a zoned/multi-speed strategy, as there are glitch points at each speed-step. (You can find this demonstrated in error-rate scans for yourself, and on most testing sites.) The format's error correction strategy "conceals" these glitch-points from the user, though they often cause speed reductions around those areas. Why burn slightly damaged media at the start just to shave a couple of minutes? You only burn once, but you (hope to) read many, many times. Glitched reads can lead to skipping/stuttering movie playback, slower than necessary program load times, or even premature media readback failures. Pioneer DVR-108-109s can burn at 6X without using zoned speed switching, I don't know about the newer models. Non-Pioneer drives tend to lag in the maximum "safe" speeds by a tick, though I'm sure most are up to 6X at least by now. I think some manufacturers call this Zoned CAV (Z-CAV).
