Adobe Premiere 6.5 and final cut pro 4

hello can you help me too i recently bought a d,a upgraded to 1ghz duel 1 gb ram but when i try to capture video on final cut pro on os 10.4.9 i get dropped frame error how can i get round this am i doing some thing wrong or is it a software problem i know its only a copy of final cut pro not a legal version would using a copy of final cut pro hd solve my problem? as i here it is possible that their is an issue with 10.4.9 i am using adobe premere 6.5 which has dropped like 4 frames in the full length but still captures the video how can i resolve the drop frames issue in final cut prowould allocating more ram help????

i am conserned that my upgrdaed digital audio mac is not up to the job of editing video duel 1ghz processor 1 gb ram i have two hard drives one 80gb hard drive for the system and a 250gb hard drive for the video capture i cant see dropped frames on my digital 8mm sony cam corda but the dropped frames seem apparent on the mac. would setting more ram to the application help more.

i have been also exsperiencing problems with quick time too

im using a firewire connection 400kbs

because the machine bus is decreased could this affect capture due to the upgrade? i think its a giga bite upgrade

i have had to mount one hard drive the 250gb one upside down could this affect the system?

as ive decided to add hard drive coolers on the hard drives

any advise where i might be going wrong?

also tryed adobe premere but in this it keeps crashing too should have i gone for a quicksilver native processor machine in stead instead it seems to spend a long time to load up premere or final cut pro

one other question i also added two hd coolers but attached the power source for both coolers on the same connection on one hard drive would this affect running speed of one of the drives?
