Mini DVD-R Samsung camcorder file type problem

[SASA39]

Few months ago I have bought a Samsung Mini DVD Camcorder type: VP-DC171
Camcorder has no USB to PC connection possibilities, other than via PC TV video card, which I do not have on my PC.
It only has a triple red –yellow – white audio/video connection to connect it to the TV.
Along with camcorder I have bought a pair of Mini Verbatim DVD-R discs.
In the user manual there are following characteristics:
Video signal PAL
Recording Quality XP (about 9Mbps), SP (about 6Mbps), LP (about 3Mbps) – I have used SP mode.
Picture Compression format MPEG-2
When I shoot some material and finalize it, I can play that same material without any problems on my TV through my camcorder DVD player.
But when I put a Mini DVD-R to my PC it becomes invisible!
Physically it is there – I can see an icon that PC DVD is loaded, and when I do a right click mouse to properties card, there is a picture showing that a disc is full and finalized.
But again:
None of the following programs does not see the disc (they only see a blank space at the F: drive-DVD drive):
1. Total Commander
2.Windows commander
3.Daemon tools lite
4.AVS DVD Player
5.G Spot
6.Kate`s video converter
7. Power DVD
8.DVD Decrypter –can see physically the disc, but not the files inside it.

I have downloaded a driver for that gamma of models directly from manufacturer’s website, and installed them.
My DVD drive model is Pioneer 111 .It does not have a newer firmware that that which are already inside it.

My question is:
Is there are any possibility to make a material on Mini DVD visible in my PC without TV video card , and what is the appropriate program ( freeware by any chance ) to convert that material to some type of file that could be visible to my PC without any problems ( avi , wmw , …………) ?

if it plays in a standalone to the tv ok, but not in the pc drive i would suspect the pc drive is going bad. the 111 is a bit old at this point and replacing it might not be a bad idea.

Hm , the least expected answer , but thanks anyway...........

try the disc in another pc's drive, if it works then the 111 needs replacing.

Beside that 111 I also have a LG DVD player , it is older than 111, same things happened.
Anyway I will try the suggested and post a report.
Thanks
