I have a buffering problem.Some times it only happens a little, somtimesmore often, and sometimes I have to give up watching all together.It happens mostly when I'm watching a video from Youtube,When I'm watching a TV program on Hulu or streaming a movie from Netflix It never happens when I'm watching from a DVD. I'm running Lenovo Idea Center. 64 Bit. I have 4 memory slots, only 2 are full with 2048mb each. Would adding 2048mb of memoryto the 2 empty slots fix the buffering problem?. Is there anything I can do to stop the buffering while I'm saving up money for the new memory? Can anybody suggest a good online store to get the memory from. Thank you.
