Hi, it's a Sony DRU-800A. I tried burning at 2.4x and it still burned at 6.1x. This doesn't happen with Nero. Here's the log:

as you can see neither 2.4x or 4x are speeds that are supported by the drive so it defaults to a speed that is supported (I 01:47:46 Destination Media Type: DVD+R (Disc ID: MCC-004-00) (Speeds: 6x, 8x, 12x, 16x)

its nothing to worry about, make sure your firmware is up to date

 

Nero doesn't always report the correct speed so if you use nero look at the burning time if you in fact did burn at 2.4 then the time it took would be around 20 minutes ( a guess)

You can see here that your drive is reporting that it can burn these discs at 6x, 8x, 12x & 16x only. For whatever reason the firmware does not support burning below that speed :)

Is there a way of letting imgburn only give those options (supported speeds)

for user's to choose from ie greyed out til media is identified then given choices determined by media/drive??

 

btw I have just dl'ed v.1.3.0.0 and haven't really gotten the chance to tool around yet so if it's already available. ignore the imbicile :)

Thanks. I never knew there was a minimum speed limitation. I think I do have the latest firmware though (KY06). It was released in November.

It?s not just the drive. The media tells the drive what speeds it supports. Use different media and I?m sure you?ll see a variation in supported speeds. e.g. If you placed some Ritek G04s in your drive, supported speeds would likely be 1x , 2x and 4x.

Honestly? I don?t see the point even though (from a non-programmers point of view) it would be do-able by grabbing the info from the inserted media and greying out non-supported speeds. Not much would be gained for alot of work and it, in my opinion, would be just something else to go pear shaped. Besides, there?s not much point buying hardware and media capable of burning at 12x or 16x and throttling it to 4x. Not these days.

 

In a nutshell, if you have a decent drive with good firmware and good quality media, burning at high speed isn?t a problem. :)
