Recently my friend got an IDE Pioneer DVR-115D dual layer burner. If you don't know its advertised speed on dual layers is 10x. He bought a stack of DL TDK 8x discs to burn a bunch of movies. The drive can't go any faster than 1.9x and the device buffer keep flashing between 30 and 70% (never 100%.) The system buffer always stays at 100%. We tried a stack of older Memorex 2.4x dual layers and they burned at 2.4x, without any buffer issues, buffers stayed at 100% the whole time.
AMD Athlon 64 3700+
160gb SATA hdd (can't remember brand)
2x older DVD burners (not dual layer, Sony and Asus)
Now I read that setting the the IDE channels to "DMA if available" fixes the problem, but it didn't make any difference. I also tried unplugging the other 2 burners because a guy at work told me that has worked for him in the past on slow burns.
My guess is that the TDK discs are bad, but I didn't think new discs still had such bad issues though I'm not an expert in dvd burning myself
So does anyone else have issues with TDK discs? do they have a bad reputation?
