A cautionary tale re: Ritek. I've burned about 600 DVD's thru mu Pioneer A04. All purchased from the same source on Ebay, that also has a store. I would burn DVD's, and then check for integrity with my Apex 1200. All was right with the world until a couple weeks ago.
Several months ago I started converting my DVD's to DivX. Went through several cakeboxes, with about a 95% success rate on burns; I can live with that for cheap media. HOWEVER, when I lent a few out, they could NOT be played, or even read by three separate computer DVD players, all less than a year old, with LG, Sony, and HP CD/DVD drives. I traced the problem back to one particular cakebox. ALL other DVDs I made are fine, and play in all machines. I emailed the gal at XXXXX, and her response was "Sorry, you purchased those over a year ago. We will not replace". What a PISSER...
While I could leave some negative feedback, I'm not sure its worth the hassle. Better to vote with my Vias card elsewhere...
BTW, I have NEVER had Pioneer media fail to burn, or fail to play in anything it is inserted within. I just hate paying those prices...
