Thanks again again again LIGHTNING UK! - Probably worth a shot I guess... will report back.

Aha! You CAN get DVD-R DLs - so would that be a possible route forward, or at least worth trying?

Thanks again LIGHTNNG UK! It's nice to get a response from someone that knows what they're talking about ;-) Do DVD-R disks experience the same rounding issue? As you can't get DVD-R DLs it sounds as if I'm stuffed either way - I guess I'll just have to be ultra-careful with my original satnav disk in the car! Cheers, Shades

I've now tried writing this image on my Pioneer DVR-215 as well as a Sony 5260S - and get identical results, with the image being written incorrectly sized. I could try a Pioneer DVR-216 and an LG unit as well, but am worried that it'll be the same. Can anyone assure me that this won't be a problem on all drives, and I should be able to find one somewhere that doesn't "round up" the size of the disk? Many thanks for any help or pointers... Shades

Ah - thanks Lightning UK! Any recommendations or advice on current drives that possibly wouldn't suffer from this problem?????

After producing a larger number of unusable Verbaitm DVD+R DL disks than I can't really afford, I'm turning to you guys for help and guidance. I've recently purchased a set of updated maps for my Lexus navigation system - at great expense - and ideally I'd like to archive the originals (4 of them, for different parts of Europe) and use a copy in the car. However, I'm really struggling to duplicate the DVD properly so that the nav system recognises it properly. Background on what I'm using - Pioneer DVR-215 (fw 1.19) on a Windows Vista Ultimate machine (Q6700, lots of RAM and disks!). The original disk information (from the right-hand panel in ImgBurn 2.5.2.0) is as follows: PIONEER DVD-RW DVR-215 1.19 (ATAPI) Current Profile: DVD-ROM Disc Information: Status: Complete State of Last Session: Complete Erasable: No Sessions: 1 Sectors: 3,064,574 Size: 6,276,247,552 bytes Time: 681:02:74 (MM:SS:FF) TOC Information: Session 1...

Can anyone help me, or point me in the right direction please? Whilst I have a few DLs left I can see them quickly vanishing in a puff of cash if I just use trial and error on this. Many thanks for all and any help. Shades
