swt7900,
The problem is there is no quality control in the making of their disks and they manuf the disks as quickly as they can. They use the cheapest dyes also
CMC is the culprit. Memorex buys media from various manufacturers to resell. Over the past couple of years CMC has been the major supplier for Memorex. The CMC is the media that gave Memorex the "black eye". Be careful though, Memorex isn't the only company that sells CMC manufactured media. I hear that even Verbatim sells some of it as their less expensive offering. There appeared to be compatibility issues with the CMC as well as quality. If they're playing and working okay, don't worry, they can't cause any physical damage I'm aware of. The problems manifest as playability errors or recording problems. In such a case, just getting some good media should remedy the problem. 4X is pretty much a thing of the past, so plan on using 8X or the 16X as the market dictates. Finding 4X can still be done, but it's like a scavenger hunt.
I'm not sure what are the opinions for Go-Video, but I had bad experience with it. I returned it the first time thinking that it might be a defected dvd recorder. Got the same model and still have the same problem. The problem was that it wouldn't recognize my DVDR (Verbatim). Since it couldn't recognize my DVDR, it would spin my DVDR and it would take about 5 mins. To resolve this issue, I have to unplug my DVDR to restart over again. I do hope it's not the same issue. Unfortunately, I can't recall the model number. Hope you have better luck then me.
