Except for cabbage-face (which really got taken care of by a LiteOn update) and the occasional "jerky movement" thing on the three and four hour speeds (which seems to be heat related), my machine records just fine and with a really nice picture. Even the three and four hour speeds look very good except when the strobe-effect shows itself.
Media? I use some no-name discs with the logo of the same wholesale club I got the machine at, and they work PERFECTLY. Only two disc rejections so far in the whole spool (100 discs, about two thirds used so far). No rejections by my other machines either, except a very old one that apparently can't play either +R or -R.
Sorry you've had a bad experience, but I'm VERY satisfied with mine so far. If the strobe-effect can be completely corrected, I'll be as happy as a clam.
Get a clue? Thanks, I've already got a whole lot more.
