I purchased the Pioneer-420H 80GB DVD recorder yesterday. Quality-wise, I'm very impressed, and the frame-by-frame editing is great, but I've got a problem with one thing. I've recorded some music videos off of Sky, and I'm trying to burn them to a Datawrite 8x DVD-R, but when I try to play it in both my computer and my PS2, it's recognised as a blank disc in the PC and not recognised at all in the PS2. I'm somewhat concerned, as in the manual, it states "DVDs can be played on other DVD players", and this is a big feature of the recorder. Thing is, that the disc plays in my Pioneer player, but each time I've made an edit, it freezes for a second or so, as though it's reading the files off of the hard drive. Perhaps I'm just doing something wrong? The media I'm using isn't one of their promoted brands, but it should still work. Any help is appreciated, cheers.
