請問您是指anyone網友還是我? G04 品質在國外評價不錯阿. I also burn 8x using Optodisc (遠茂), Prodisc (精碟) 片子. I think you must be saying G03 cause may people have trouble using G03. I do not have Liteon DVD drive or writer so I cannot do PI/PO level test.

不知道您指的是不是我做的測試.....如果是的話
有些地方可能要說明一下...免的誤會了

1.2片均是以8x燒錄完成....4.37G Video_ts資料夾
2.關於M Code的部份....A07讀的是G04...2500A讀的是G05....買的時候店家說這是8x片(滿貴的)...市售的Ritek 4x DVD-R不管用什麼機器讀都是Ritek G04
3.4x的DVD-R還沒測試A07 8x燒錄的結果.....
4.PIPO測試為求比較精準的效果....所以用811S , 4x Speed , ECC設8作測試.....不過不同的PC環境測出來可能不太一樣

有人做的測試

I think G03 and G04 all suck. But G04 is better than G03.
and G04 is better than 國碩,利碟 4x -R.

So I use 國碩 2x -R , or M-Star 2x -R (AZO) , it is cheap. but slow....

If some of your friends have liteon DVD ROM or DVD writer ,
you can bother him with some PI/PO test.
G04 is disappinted with me . It is " Ritek " .
But Ritek +R is good .

Mmm...I will purchase Liton DVD-Rom 163 EIDE tomorrow and do the PI/PO test.

Here is the info obtained from DVDinfopro for the G04 I use

Here is a link of people's testing of Ritek's DVD-R: http://club.cdfreaks.com/showthread...&threadid=75447

I guess you might be right, the PI/PO values go up at the end from people's results, and probably my result will be similar. I think I should not say in my initial post that it burn at 8x to the end because it showed 7.8x. (I was shocking to see that it just took 8 mintues and 24 seconds to finish a disc <4,571,138KB, movie -The Patriot> so typed real fast)

I will keep you posted.

Here is another link of people's feedback of Ritek's DVD-R 4X G04

http://www.dvdrhelp.com/dvdmedia.ph...dia=94#comments

RITEKG05? 那這片是 Ritek 8x DVD-R.........
因為 Ritek 把 pre-pit 刻 G04, pre-write 刻 G05.
如果燒錄機在燒之前讀取片子資訊沒去讀 pre-write 區域的話, 是沒辦法認出 G05.
難怪 PI/PO 那麼低....真正的 G04 應該不會那麼漂亮.

使用碟片 買滿久的Ritek4x DVD-R


DVDInfoPro資訊


燒錄時間


PIPO測試


燒錄面1....4x to 8x......有明顯的同心圓


燒錄面2....8x to 8x......無明顯的同心圓


上班偷作測試之心得
1.目前僅測試Ritek之DVD-R....其餘的公司沒放片子不知結果如何
2.版面有8x之碟片不論PIPO值或燒錄面之顏色均較4x 之G04好滿多的....看來買對片子但是新台幣不見了

題外話:Sony 707 拍的比Casio EX-Z4好耶...還是自己技術差ㄋ

看來要燒 8x, 還是買 8x 的片好
-R 是這樣
+R 也應該是吧

貴一點但是品質好

G04 尾圈 PI/PO 總是升高 ...
末端品質也不會太好了
所以不喜歡 G04

謝謝前輩指點,但我依樣更改,但總是顯示裝置未就緒.(could not open derice F:r7100007.105)等訊息.不知何處有誤?請前輩指點.謝謝!
