Bizarre error using TMPGEnc 4.0 Xpress?

[the colonel]

All I want to do is convert some DVD-RAM material to DVD-R...

No problem I thought, download the trial version of TMPGEnc 4.0 Xpress on my desktop (running Vista) to see what the conversion quality it is like.

Using the source wizard to import the clip from a DVD-RAM disc I get this error message:

Unsupported File (error code 0x80048003)

Not a good start and searching the net provides little information on this. Importing other formats on disc such as WMV works fine, the issue only appears to be with RAM.

I downloaded TMPGEnc 4.0 Xpress to my laptop which is running XP and using the same disc the source wizard recognises it and imports the file, no problem.

I then check to see if it is a hardware error with my DVD-RAM drive by connecting an external drive to my desktop PC, still no go, same error meessage as above. Just to check the external drive also works with the laptop, TMPGEnc recognises the file.

On my desktop if I copy the complete 'RTAV' folder to the hard drive and using TMPGEnc I import the VRO file directly, this way it recognises it allowing me to do the conversion!

There we have it, a rather sorry state of affairs, hopefully there might be some ideas on what could be wrong?

There seems to be some conflict with the TMPGEnc software, because a few weeks ago when I tried the authoring software that would not recognise the DVD-RAM discs either.

Thanks in advance,

Just had the same error code and couldn't work out what was wrong.
I even downloaded the software again.
It turned out to be that I didn't have the decryption software running (AnyDVD) after I started that up, all was good again.
