Was noticing that smearing on the Revivax and DJ's test clips. It really isn't present on the LDs. (from what I recall)
BTW: what method did you use on Mac for this? I used one while at school with an old LD player and FCP-which didn't work out well at all...the captures looked awful no matter what I did to them. Not to mention that trying to add the 5.1 ac3 was a nightmare b/c FCP does not accept ac3.
