The whole point of a buffer is to create a "safety zone" for all the info whilst it is being processed for burning. If a slight error occurs, there is a nice buffer for the burner to fall back on whilst the info is re-assimilated. The bigger the buffer the better. hence some HDs have an 8mb buffer, others have 16mb. the same goes with burners. That is what capacitors are for, they help smooth the flow of electrons by storing them for fractions of a second, then releasing them slowly to reduce voltage spikes in your system.
If you didn't have a buffer you would get write errors. this goes for when encoding the info onto your HD too!
A buffer will not harm your HD, or anything else for that matter! They are absolutely VITAL to keep your PC running smoothly!
I would suggest reading up on how a PC works! They are relatively simple, but there are a few basics that you need to know. This knowledge that you glean will give you greater power in sorting out any problems that you have.

hi

and if a buffer under-run occurs most software these days can see this and re write that specific spot before finalization occurs, hence saving your dvdr, if you have a high spec pc then mutitasking should be ok whilst burning... i do allsorts at the same time and find it good.

I understood it but with a newbie that asks about the buffer level being to high I just think it went over his head lol

what I am asking is: is buffernig caused by low processor speed or harddrive speed and does buffer in some way does something to the data?

It ABSOLUTELY does have to do with a slow processor.

Yes burrning is effected by processor speed and RAM. Actully so is encoding the DVD to be burnt.

Somone with lets say a 3Ghz processor could do alot more multitasking with somone that has a 900mhz processor. Cause the 3Ghz processor is faster and can keep up more with the information its sending and recieving. Same with RAM the more RAM the faster the processor can send and recive information.

So when you watch the buffer level and its at 100% that is a good thing. It is working smoothly.

You need to worry when the buffer level lowers and completly falls out that is when you will get write errors or even a failed burn.

This happens cause the processors usage is being used somwhere else and if the usage is high enough all the information that the buffer has will be used while nothing is being wrote to the buffer so the level falls (the buffer empties) and then has no more information to burn cause the CPU cant keep up.

This is uasly caused by mutitasking while burrning or other programs running in the background. So if you have a slower processor or RAM then it could effect the buffer level staying at 100%.

If you have problems keeping the buffer level full at 100% then you need to

1 either get a faster processor and more RAM

or

2 dont multitask during burn and stop any programs that could be running in the background so they dont effect the burn.
