This is my first post here, and after about a month of lurking around this forum, I would like to take a few minutes to share something I discovered about my xbox.
note: I just recently modded my xbox a few days ago, but my tests were done during the boring time time when I waited for my Matrix chip.
I bought the xbox sega bundle about a month ago, in Toronto - Canada. Using pics posted in these forums, I verified that is has a Thompson DVD drive.
I read many times in either tutorials, faqs and in messages that CDRs would NOT work in xbox (except for those with Samsung DVD drives). I bought a bunch of Princo CDRWs (which read fine in xbox) without even trying CDRs. But out of boredom and curiosity, I tried putting in some old audio discs that I burned on several different CDR media. All of these were burnt at 4x, because my old HP burner maxes out at that speed.
Result: about half of the media I tested worked perfectly, while half would not read. The ones that worked are Princo (white label), Gigastorage, silver tops (probably some are Princo too). Some that did not work included Acer, RCA, artmedia, and TDK.
So while CDRs "do not work" might be true for many xboxes, it is not a fact for all xboxes!
Hope this might benefit some people who didn't even try using CDRs, such as myself (before I did my little test).
