Why are my videos and voices so choppy?

[Jihad]

Thank you for the helpful replies! I also have the 5XXX PSX I can work with as well. Do the missing ball bearings on the CD holder make a big difference? Some of the black plastic is also missing. Would it be better to mod this system or the 1XXX system? Being the 1XXX system, I am afraid the sucker is going to overheat (I think sony had to recall the early models). I would rather not tweak with the laser as I would not like to permently damage the system. Also, do 80-min CD-Rs have anything to do with games working or not working? Do the later systems work better when modded? Mod chips are do-able. Do you have any preference for a preticular mod-chip distributer? I will obviously go with a stealth chip if this is so. Thanks again spooky and everyone else who posted for all the helpful info.
