Lap Top DVD

I have a DVD -CD drive that runs a typical DVD just fine. I am using WINDVD on this unit and XP.
My problem is I have a disc that is a copy of a disc that was copied from the TV and recorded on a DVD-R disc that will not run on the laptop at this time.
Now the 1st copy I was able to run on this laptop about a year ago and have since received a copy of that disc and I have struggled with trying to run it. I have to carry a DVD player to class just to run this one disc. Not the end of the world, but It sure would be convenient to be able to run this DVD on the laptop-Projector setup.
Please use the KISS principal in any answer.:smiley:
Thank You

Aren’t many TV shows and things encoded in such a way as to make it possible to make one copy but not make a copy from that copy? Or did I imagine hearing that?

I was wondering if there was some degrading when a copy is made.:dubious:
When I ran the 1st copy owned by an associate instructor I did struggle to get the disc to run but that might have been not waiting long enough for the thing to load as the drive is busy(drive light on) but nothing happens on the screen.

The first test would be to try running this 2nd generation copy in other players. If it will not play anywhere, I suspect it either was not burned correctly or it is disabled somehow.

Many notebooks esp. those 2+ years old, cannot play the full gamut of DVD recordable media varieties. Some will do DVD +R some will do DVD -R but not both. 1st copy was likely a DVD +R which your unit will play, this copy is not. Get an external USB based CD-DVD multi-player recorder/burner and make a copy of the current DVD using the external player as the source and the internal DVD unit as the recorder.

www.anydvd.com has good DVD cloning software

What is the precise make & model # of your laptop?

The unit is a Twinhead 8750
I will have to call the friend with the other copy and see if it is a DVD+R.
Of course, I knew nothing of the difference in discs like that +'s & -'s:smack:
The Drive in my unit isn’t a DVD recorder unfortunately.

This laptop is only used for Gun training classes w/ PowerPoint show’s and video’s.
Thank you and Astro you are the best, as usual:)

The disc was indeed the problem! It has been copied to a DVD+R and now runs just fine.

The friend that did the new copy thinks the + & - are related to the drive rotation direction. Is this true??

Thank you very much:)

No, I’m pretty sure the drives all rotate the same way.

The + and - are merely indicators of differing formats.

Here’s some details: http://svp.co.uk/helpdesk/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=69

Thanks for the link KTK,
I sure didn’t know all that + & - stuff about the optical drives and from what I could gather from your link the +R is more the odd-ball, just like, well anyway I just took out my manual that came with my laptop and there is nothing in this about it having any +R compatibility???

Thanks again all
Greg
