Page 1 of Copying DVDR Recorded Disks on the PC

OK - quick (& possibly dumb!!) question.

I can happily record from SKY+ to my 4KUS DVDR - however when I then put the disk into my PC and try to copy it (using DVD Shrink as I would for a bought disk) it fails - telling me it has an "invalid navigation structure" ....

Can I copy DVD Recorded disks some other way in the PC ???

Well what type of DVD is it? :)
Try DVD decrypter it handles finalized DVD+R and( no finalizeing needed) DVD+RW as well,it will also let you burn them to your PC DVD burner. :)

This has nothing to do with finalising discs, guys. A good number of DVD recorders don`t produce fully DVD compliant discs, even when they`re finalised, and they trip up DVDShrink every time. As DVDShrink would actually only be copying the files and not doing any processing, you don`t need to put it into the loop. Just make a folder on your hard drive with an appropriate name, then get the contents of the DVD+R up on screen. You`ll find two folders on the disc - VIDEO_RM and VIDEO_TS. Copy them to the folder you`ve set up on your hard drive. They`ll take between 8 and 15 minutes to read across depending on the speed of your DVD-ROM drive. Check the files work, then burn `em to a blank DVD+R with ImgToolBurn (or whatever burning software you use).

Has anyone in my family ever suffered from insanity?
No, we`ve all enjoyed it immensely.

Thanks mate!!! Will try that tomorrow.

if it`s been created on a set top recorder, just load nero (or whatever burning prog you use) & click "Copy disc" :D

or am i missing something :¦

Works a treat - Cheers Mark

Or even quicker use DVDdecrypter in IFO mode, this will result in showing you the PGC of each recorded title, from this you can also then elect which chapters you want to rip whcih is handy if you recorded a 1 hour programme but let it run on for longer.

Also the way that the VR format works you will see that a straight copy of the Video_TS folder of for example a 1 hour recording in HQ mode will cause a transfer of about 4.2gb, in IFO mode and transferring the PGC the transfer is only 2.1gb. This is because the VR format makes a duplicate, I presume for editting reasons.

As far as I can ascertain, the VR format writes a temporary set of IFO files to the VIDEO_RM folder on the disc (recorders don`t bother making an AUDIO_TS folder). The VIDEO_RM folder is written in the first half millimetre of information at the start (hub) of the disc, in a narrow gap ahead of the video information. Your recorder reads the IFO files in the VIDEO_RM folder to navigate the disc before finalisation. When you finalise the disc, the IFO information is written to the gap before the video data track, as part of the standard VIDEO_TS folder. You can drag and drop the VIDEO_TS folder to your hard drive and it should work like a normal VIDEO_TS folder.

I`ve noticed a number of DVD recorders run into the "invalid navigation structure" situation with DVDShrink, although my old Philips had a firmware upgrade which sorted the problem out. Both the 4KUS I had and my current CyberHome produce discs that DVDShrink doesn`t like, but once the VIDEO_TS folder has been dragged and dropped to hard drive, Shrink will work with them.

The last week or so, I`ve been using Ulead Movie Factory 4 Disc Creator to re-menu a bunch of home recordings. That imports the files direct from the DVD and converts them to .mpg files which I can then edit (delete adcaps), or even pass through VirtualDub to eliminate those pesky onscreen DOGs (you need a lot of storage space on your HDD if you want to do that).
