I've watched the Matrix RiffTrax several times with my DVD player providing the video and my iPod or MacBook Pro providing the audio. Each time, the riff becomes out of sync at the same point.

Last night, I watched this riff again, but this time using a combination of my MacBook's DVD player and iTunes. This time, no desyncing occurred.

Maybe the flaw lies instead in my DVD player, an early model Panasonic A120?

I found, as you did, that a 3-4 second drift introduced itself around the time Neo visited the Oracle. I had synced the film and commentary perfectly at the beginning of the film and had not paused either, so it's definitely an inherent flaw in this particular track.

My movie buddy and I didn't pause either X-Men or The Matrix, be it for phone or bathroom breaks, mostly because we didn't want to re-sync. :-) He owns Daredevil on DVD (I'm not sure what version — the RiffTrax works only with the non-director's cut), which we saw in theaters when it came out four years ago next month, so we may spring next for that commentary — which has the distinction of being the first RiffTrax to simultaneously feature all three alumni of MST3K!

BTW, what was your audio hardware setup for watching The Matrix?

My family and I tried out RiffTrax last weekend, by renting The Matrix and purchasing the RiffTrax MP3 for that movie. It was actually very well done, and the commentary was very funny. My comments on the process are that it was difficult to keep the movie and MP3 in sync with each other. Not only did the telephone ring several times during the movie, requiring both being re-synchronized, but there is some drift that seems to happen anyway. The script notes that were included with the MP3 gave clock times for both the MP3 and the DVD to allow re-sync, and where there was a 2 minute 10 second difference between the times at the start of the movie (2 minutes used on the MP3 to introduce the movie and give instructions), by the end of the movie it was a 2 minute and 13-14 second gap. So even if there had NOT been any interruptions, I would have had to resync anyway.

Despite this annoyance, it was still enjoyable. I am considering listening to his commentary on The Fellowship Of The Ring in the near future (since I already own that movie).
