i have been experiencing this problem for quite a while now, hopefully i can find the solution to it here 
1st i normally convert downloaded movies to mpeg using TMPGenc and then burn to VCD's using VCDeasy.
Playback using my standalone Panasonic portable vcd player is all fine.
But when i pop the vcd into my Sony 3-disc VCD player all hell breaks loose, i will have problems like jerky videos, sometimes it will just seems to spin forever unable to detect anything at all. I tried playing VCD's bought from the local store and all is fine.
Has anyone encountered this kinda probs and solved it??
thanks in advance
