This ONLY happens in 720p50 mode, thus only with PAL dvds. When we set the HDMI output to 1080i or 576p, this problem disappears completely! It's annoying since 720p is the native resolution of the Z2. There is absolutely no problem with 720p60 so NTSC disks look stunning.
The strongest example I saw so far is on the MK2 edition (region 2, PAL) of Elephant (Gus Van Sant): title 1/8, chapter 6/37, time 0:10:55 very visible on the white vertical bar created by the sunlight through the windows).
ALL our PAL DVDs exhibit this problem.
Oppo wasn't too interested in this issue. I'm wondering if it's a problem on the Z2...
Any help appreciated.
It sounds like you're experiencing an effect commonly referred to as "tearing".
Perhaps your TV TYPE is currently set to "AUTO", which would cause the 983 to send the disc-sourced format direct to your display without conversion. If so, you might try setting your TV TYPE to "NTSC", thereby forcing the PAL=>NTSC conversion. (Assuming from context that your display is NTSC).
Additionally, as per an earlier post, you can sometimes improve upon the generally excellent "AUTO" De-interlacing mode by selecting the "2:2 odd" mode for most PAL film-sourced material.
Hope this helps...
