This may possibly be a user issue or a 12.04 issue. I just burned a 4.02gb DVD last night on 14.04LTS(ISO, one file), and have several times burned 4+gb general file DVDs using Brasero, and have had no data loss or errors as a result. The only problem I have ever had was trying to use Brasero in writing video files (due to other dependencies related to video time stamps). Brasero gags on time stamps really badly.
Then again, terminal command line mkisofs is the best way to handle writing video DVDs, anyhow.
just create a directory called 'junk', with two sub-directories, 'VIDEO_TS' and 'AUDIO_TS', copy your target files into the video_ts folder, then:
mkisofs -dvd-video -o junkimage.iso junk/
this will make you an ISO image of the DVD that you can burn however you want to. If you get errors, check 'askubuntu' for video format errors and PAL vs NTSC format setting, as well as looking up what the significance of the Video Manager Information File has.
Ok, I took an old video DVD, placed it on my harddrive (in DVD .VOB/.IFO structure, with .BUP files too), total size was 7.9-gb on-drive.
Then, using mkisofs, I followed the generally accepted practice as follows:
- Made DVD folder named 'DVD' (HOME/TEMP/DVD)
- Created two sub-directories, VIDEO_TS and AUDIO_TS (beneath the structure explained in step 1).
- Placed all .IFO and .VOB files in VIDEO_TS (if you have audio files too, like .AUP, they go in the audio sub-directory), leaving the .BUP and management files in the /DVD folder itself.
- opened TERMINAL, went to the directory given in step 1
- type in the command:
mkisofs -dvd-video -o dvdimage.iso dvd/ (you will change the .ISO filename and the dvd/ folder, depending on the name of your dvd. If your dvd was named TROLL, then the command would be:
mkisofs -dvd-video -o TROLLimage.iso TROLL/
- Now, I have a 7.4-gb ISO image sitting in 'home/temp' by the name of dvdimage.iso
- Open Brasero and select the last button (BURN IMAGE), choose your ISO file, choose your destination (ideally, your DVD drive), and accept. When done, you now have a new burn of a video DVD that will play in a DVD player or DVD drive
My test on a 7.4-gb .ISO onto a DVD+R(DL) dual layer disk (capacity 8.5 gb) was successful, and I did play the movie afterwards (I also wasted almost 2-hours watching the movie, afterwards!)
I did get one initial error when my typing hand decided that I spell 'dvd' as 'dwd', but a quick OPERATOR ERROR check fixed it...Ubuntu performed flawlessly, as did Brasero.
If you get errors, look hard at yourself first, then make sure that you have PAL or NTSC (as may be required in your region) set properly, if required. Also, if you are not placing your appropriate files in the right place during the mkisofs process, you are mostly likely failing at this point. Remember, you must build your directory structure first, to successfully use mkisofs for video dvd processes.
