Amazing, very good work 
Thanks guys !
Here are some answers:
By the way, can we now also play LD games on the Pioneer PX-7 UK version, which is PAL?
The Raspberry can output PAL, you just need to edit boot/config.txt
sdtv_mode=0 Normal NTSC sdtv_mode=1 Japanese version of NTSC – no pedestal sdtv_mode=2 Normal PAL sdtv_mode=3 Brazilian version of PAL
Tried that here, it's real PAL & 50Hz (black borders & grey MSX display proves it):
So it should work "out of the box". Maybe the video could be transcoded to 50Hz for sync & performance sake.
The Raspberry Pi Zero (for $5) is usable for it ?
PiLD need two full-speed threads (one for listening to the MSX, the other to decode OGV video), and composite output that the MSX can mix. The PiZero seems single-CPU and HDMI only, so this does not look easy (but I must say that $5 is an incredible bargain !).
Perhaps I should get my PX-7 UK version out of its box then
Nice .

Let me know if you go for it, I'll provide you the installation instructions & wiring (dont' want to make it completely public yet). Or we could give your PX-7 a try at Nijmegen if you bring it with you ?
i use a monitor < nms8280 < px-7 < hb f9p video true.
?? Not sure to completely understand. You have all those machines linked through video super-impose ??
Anyway, support for the NMS8280 & HBF9B will require more work:
- Right channel sound needs to go to the casette port.
- Commands sent from the MSX to the LD need to be redirected too (maybe the casette port too ??).
That kind of involves rewriting a modified Palcom BASIC/BIOS ROM. Not straightforward but doable (at least if the LD games do not use direct port access).
