What cheap media do you burn at 4x? As to me I normally don't burn any media (even the good stuff like 16x TY's) over 8x. However I do test media at 16x from time to time & the quality stuff (like TY & MIS Verbs) burns & tests great at that speed. Other media tests good too but not as good as TY or MIS Verb. Last month I picked up an HP 50 pack at Microcenter just to see who made the discs. Turned out to be CMC with good (I've seen better) test results. Not something I'd buy in the future as I'm not sure how long they will last before going bad. This month I picked up one pack each of Phillips, Magnavox & Memorex. All tested fine at 16x except for the Memorex which tested better at 8x. I suspect Memorex is buying CMC rejects for it's discs. I'll burn all of the CMC media I bought at 8x then go back to my TY's. Speaking of cheap media I bought two 50 packs of Windata (one +R & one -R) for $9.99 each which codes out as MCC. I'm sure it's either fake media or maybe Verb rejects since they don't test as good as real Verbs. They do better at 8x. Like I said I'll burn up all this stuff at 8x then go back to TY's. Some is going into the DVD recorder thats hooked up to the cable DVR. Ill find out later if the video discs develop problems or not. Both my DVD recorder & the DVD player I use seem to track an AML Nexxtech disc & was given plus an MCC Playo disc without problems. I didn't burn either one & they both have some of the worst test results I've ever seen. BTW my computer skips on both if I try to play them with Nero Showtime. I'm sure it's because my computer drive is reading them faster than the DVD recorder & the DVD player does.
