I started trying to burn VCD's several months ago. Many times I would burn a VCD and put it in my standalone GE DVD player - usually it would simply eject the CD, occasionally it would display "VCD", but never would it even begin to play the VCD. Then I recently tried it again and burnt to a CD-R labeled "GQ Great Quality" "80min 2x-12x" and it played just fine. When I ran out of those, I used CD-R's labeled "GQ Great Quality" "32x 80min" assuming them to be similar. Indeed, those also worked just fine, that is VCD's play quite well, but SVCD's play for a while then begin dropping several seconds of program at a time. I assumed this to be a shortcoming of the not-very-new DVD player. Okay - then I saw your reference to CDRIdentifier. Out of curiosity, I looked at the GQ 12x and was given the following: ATIP: 97m27s28f, Disc Manufacturer: Princo Co. Recording layer: Dye(Short strategy; e.g. Phthalocyanine) nominal Capacity: 702.83MB (79m 59s 74f/LBA: 359849). So far, so good. Then I looked at the GQ 32x expecting similar information. Instead I got ATIP: 97m26s51f, Disc Manufacturer: Lead Data Inc. Recording layer: Dye(Long strategy; e.g. Cyanine, Azo etc) nominal Capacity: 702.83MB (79m 59s 74f/LBA: 359849). So, different manufacturer, different strategy, yet they both work in my DVD player while others (including Mitsubishi, CMC, and Ritek, long and short strategies) do not work. All were burned on a Lite-On 121032 at 8x or 4x with Fireburner or Nero. Any comments ??
