Ok, I went ahead and purchased AVToolbox AVT-8710. However, I am returning it. I've tried it with my FlyVideo LifeView 3000 TV Tuner card. I plugged the DVD player and played Snell & Wilcox reference. NTSC. The video quality between direct capture and capture via TBC was very close. The images are attached. However, I then used the SECAM VHS tape. And there I noticed that when I viewed using TBC, TBC would freeze the video frame at random from about 100-200 milliseconds up to a second or more. Yeah, I would not get the dropped frames during capture as far as my TV Tuner card is concerned, but I would get the dropped frames inside TBC. The frozen frame is a dropped frame in my book. So I had to scratch this solution.

While playing with it I noticed that my capture software has perhaps something similar to TBC. I use Philips SAA713x family card and use Philips drivers (not the LifeView ones). The application software has Vertical sync recovery modes. There are 4 modes: Normal, Fast Tracking, Free Running and Intermediate Running. Usually what I used to do is I would start capturing in Fast Tracking mode and then switch to Free Running mode. That way, I don't get any dropped frames.
