I'm using LG GP08NU20 1.00 DVD_RAM. Everything was fine with the same media, burner and DAO a short time ago. I don't know the reason but now having problem with DAO/SAO type of write. I tried the "incremental" method for last two burning project with success. Long story short, 1. Does it mean my data cable(y usb), dvd-writer (hardware) are healty? 2. What do I need to write with DAO/SAO option? (Driver etc) Thanks

Yes it is cheap and ancient But working. In this situation, tried to burn with unsupported write speed. After my first post re-tried to write same but at 24X. Successfully finished as usual. BTW, love ImgBurn. Never think to try neither another nor return to previous(Nero). Thank you. Just learned new ImgBurn version. I will upgrade. I didn't know new firmware too. Also think to update firmware too. Now will research how to and success stories about firmware. Thanks again.

I have one LG DVD-Writer and one LG CD-Writer. When I was burn on DVD set the burn speed 4X. Later burned a couple of CDs with CD-Writer successfuly. Of course increased write speed too(24X) for CDs. Yesterday I started to burn CD with CD-Writer but ImgBurn was selected DVD-Writer in droplist at startup. I don't know why wasn't set latest setting. What so ever, I switched to CD-Writer from combobox. Began to write. Unfortunatly couldn't burn, failed. Looked at ImgBurn log. This is what I saw: I 02:47:06 Source File Application Identifier: ImgBurn v2.5.1.0 - The Ultimate Image Burner!

W 02:54:11 Retry Failed - Reason: Cannot Format Medium - Incompatible Medium W 02:54:11 Retrying (2 of 20)... I understood that because of low write speed. I was forget to change write speed. Is there an option to switch whole settings between two different writers? I hope explained enough. One more thing, I don't use MAX speed any time.

Good news. Successfully burned approx. 3.5 GB data to Princo DVD-R. Burned 4X and verified too. Only burning took 1 hour and 51 min. I did a Discspeed test. But couldn't understand much. For example read test was X 0.67. Two colour graphs was almost parallel. One is a little bit arise. Burner is LG GP08NU20 (AZCR10B). Any suggestion? Especially about quality and trust. Thanks again.

Excellent explanation. Now understood. Didn't know this issues. In my situation, suppose, better is trying to burn but not trust. I have a LD CD-Writer too. I will burn same data both CDs and DVD once. Than will test with different DVD readers. If there is no more option. Thank you very much for everything. ImgBurn, support forum, helpful replies...

Thank you. ImgBurn is my prefer until my first try. I don't have USB 2.0. I have USB 1.1, I suppose. What did you meant by lower quality burn? Vids? I want to backup couple gigabyte data.

One of my friend gave me his LG USB DVD writer. System requirements read on box higher than mine. I have P3 450 MHz, 256 MB. BTW, I tried a write test with ImgBurn 2.5.1 For my surprise test finished succesfully. Now I wonder writing will be successfull? Also, let's assume could finish, may I trust written DVD? Wrong, missing data, TOC etc ?
