Thankyou. I did manage to get the filter working but ended up with a huge file. Then remembered to use full processing and use compression (ie. Xvid or Divx) to reduce the size of the output file.Everything was going along fine until about the last 2 min of processing when vdub decided to crash. The problem had something to do with the filter but I could not understand what it meant. Ran the avi thru dvd2svcd and it came out perfectly with no audio sync problems but still had the text at the bottom of the screen pop up. Will try vdub again when time permits and try to trace the source of the crash.
