Widescreen Review Sept Issue 64 has a 2-page article/introduction by DVE producer Joe Kane, if you can find a copy. It's pretty comprehensive. VE now is OOP.
Programs will incorporate progressive and HD mastered formats and in 6.1 audio. NTSC and PAL information will be covered. Disk demos also will show how room set-up is crucial to HT playback.
There'll be a Pro version and D-VHS D-Theater Format, too.
