LIGHTNING UK!

The drive reported a 'Write Error' that time. Try cleaning the drive with a cleaning disc and/or buying some 8x Verbatims instead of the 2.4x ones.

The 4x speed is all the drive is reporting. If the reported speeds vary if you eject + reinsert the disc, it must be having some sort of trouble reading them. So yeah, cleaning the drive may help. It could also be a sign of the drive dying. avi and mp4 aren't disc image files, that's why they aren't on the 'supported' files list.

Only being offered 4x on 16x discs isn't great. If that's all it's ever done, you should probably think about investing in a new drive. Have you tried cleaning the drive with a cleaning disc?

The buffer size and priority have nothing to do with anything. The 'write error' shows your drive has (had) and issue writing to the media you're using. Once the data is in drive's cache (buffer), it's purely down to the drive/firmware/media combo you're using. Get yourself some decent Taiyo Yuden CDs.

Your drive can't burn BD discs, it can only read them.

Do you have 'MediaInfo' installed at all? It would help to see the properties of the file you're trying to load. The filters don't work with 24bit flac files etc. Other than that, I can only assume you still have a filters issue. Did you install madFlac as per the Audio CD guide in the Guides forum?

You'd burn all CUE files the same way.

and it doesn't play? What about in PowerDVD / TMT on your PC?

Thumbs.db are normally just cache type files put there by Windows - that's why the program defaults to filtering them out of what gets burnt to the disc.

Use a new disc, it looks like you've already tried and failed to burn that one.

To me that sounds like Explorer's job.

Does the disc info look different yet? It probably won't work properly until it at least also displays the drive model and firmware version. Maybe try an older driver? If 10.8 works with your chipset, give that a shot.

I see no error in that

Try the v11.7 Intel Rapid Storage Tech. drivers, the v11.5 ones you're running there could be messing things up. http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=2557&DwnldID=22271&keyword=%22rapid%22&lang=eng

Can we see the log (showing the error) please?

"in the Log window" If you've closed it (shame on you!), open it again via the 'View' menu.

Load the program, switch to Write mode and then press the F8 key to enable I/O debug mode. Now click Tools -> Search for SCSI/ATAPI devices Once it's finished and that disc info box is filled out, press F8 again. Then click File -> Save As in the Log window and save it to a file. Upload the file here on the forum for me to look at please.

Is that a straight copy + paste of the disc info text? It's missing the drive model and firmware version You probably have a deeper system issue (controller / drivers / cable etc).

Tell us more about the source disc. What files are on it? Where's the log of the burn?

Yes, it'll include the boot sector. It reads every sector of the disc from start to finish.

I've no idea on the format it records in, but if it's not DVD Video compliant (a video_ts folder containing *.ifo/bup/vob files), your disc won't play in a standard DVD player. You might be able to convert it to the correct format using something like DVD Flick or ConvertXtoDVD.

You don't have a drive that can burn DVDs.

You should only need v2.50 If the disc doesn't work, it's usually because the player doesn't like the folder structure / files on the disc - and nothing to do with the burn itself. Post the log please so we can at least see if it burnt and verified correctly. If you're having problems getting a working disc, just use a BD-RE until the issue is resolved.

It doesn't happy to every nvidia user... I'm one and it's fine for me. There are a couple of threads in the 'Bugs' forum that provide a workaround.

When a drive returns an error, it usually also provides you with 2 numbers. Those 2 numbers are known as ASC and ASCQ. What I then do is look up what they mean in a (build in) table and display that text to the user. http://t10.org/lists/asc-num.txt
