Okay I have been having some trouble when I capture that the video freezes at parts, so I have talked to people at muvipix.com and said a TBC would help. I just to calirfy though. Do I need a TBC or VCR with TBC even though they play fine in the VCR on the TV. And I now it is not my system because I defrag my hard drive, have a AMD Athlon 64 X2 5600+ CPU and 2 gigs of memory with two 500 GB hard drives. If I do need a TBC, which would you recomend for this particular instance? Thanks in advance for your replies.

Please help.

The internal and external TBC do different things, so you probably need both. Datavideo TBC 3000 is a good one.
