It also has another two SVideo jacks and those two can also be used for composite.
It is the best sub $500 card I've used. On paper it looks like any other capture card, in use it produces much cleaner captures than anything else in its price bracket.
If you are in the NTSC world, then you really really don't want to use DV capture, in addition to limitations with the DV codecs, NTSC captures in 4:1:1 whereas DVD (and PAL DV) is 4:2:0, so you end up with 4:1:0 efectively, so you lose a *lot* of colour resolution.
If getting dropped frames, use a separate hard drive to capture to (i.e. never use your C: drive), make sure you have plenty of RAM and make sure all other programs are not running (virus scanners, any other memory resident programs) and use a 7200RPM drive, or configure a pair of drives as RAID0.
