I have 25 DVD need to burn and I have a LiteOn 4x burner. Just wondering if I burn all 25 DVD-R in a row, would it damage the burner? How many DVD I should burn at a time that won't kill the burner easily?

25 dvd's is nothing, don't worry about it... my sony burner appears to be giving up the ghost after well over 600 burned discs.

i guess that it would help if you had it mounted in a fan-cooled environment, which is what i have.

Thanks Dan, so if I burn all 25 DVD-R at once, at the same time, it won't affect the performance of the burner right? I have a fan inside the computer but will the burner get too hot? What was the highest number of DVD you burn at one time before?

I am burning 10 in a row right now on my Pioneer. ;) It should not be an issue.

I've burned 35 in a row on my Sony. Costco now carries the 8X non-double layer external Sony for $149 so I bought another. With 2 each on separate computers, I can burn all day with no problems.

Mike, you can get a Pioneer 108 or NEC 3500a (without apps) for under $80 now. That is 16X and DL 4X!
