I have a Sony DVD recorder RDR-HX510. I have made some recordings with it, dubbed them onto a DVD disc, but my PC won't play them. I have Windows media player on my PC. Do I need another piece of software?
Sometimes nothing, sometimes the PC crashes. The PC is an HP from about 2005/6, but the dubbed discss won't play on the newer Dells we have at work, either. The discs will play on the DVD. Click on the properties command on the PC and it shows the disc as full.
Also, you say "DVD" what exactly do you mean? +R? -R? -RW? +RW? Sony's DVD recordables (DVD+R/W) were not -until very recently- official DVDs as they were a bastardised format which caused problems in many ROM drives and standalones. This may also be the route of the problem.
