Sound like that infamous middle gear warmup issues. Try to move the gears by hand, practically the middle gears. They should move freely. If not, try to take them out, clean them and apply some lube. Be careful not to  break them as they can be easily broken because they are so dried.

If the gear is starting to cause problems it'd be better to replace it regardless, it seems the plastic is chemically unstable and will turn to cheese eventually. I got a replacement set of Chop.

home, took her apart, sure enough the gear seemed a lil sticky, so i used some wd-40 to clean and free it up, then applied some lithium grease, fired up, and the disc spun right up! only game i have is sherlock holmes , but so far seems to be running smooth!

why does the cdrom need to be 'warmed up' to start? technically speaking

I would suspect, that after it warms up it sorta melts what ever crap was around the gear? maybe broken down old grease? only think that would make sense to me?

If the teeth on the gear still look good then here is what you can do. Take the gear off and drill out the hole with a smaller than the size of the hole bit. Don't use a larger bit cause you could make the hole too big. Move it around from side to side while doing so and that will get all the old gunky lube out. Then re-grease and put back on.

thanks for the tip, so far its running good, i didnt have to remove the gear, hopefully this will last for awhile.
