a. I saw that film for the fifth time on the internet. Does this mean that on all the four previous times also I had seen it on the net? Let us say I had seen it twice in the theater and twice on the net and I saw it one more time on the net. Could I use: b. I saw that film for the fifth time, on the internet. Will the comma affect the meaning? Will it leave open the possibility that the four previous times were not necessarily "on the net"? That is my feeling. With the comma, the sentence seems to be saying that the fifth time was on the net without saying anything about the other times. Thank you.
