Yes, the signal from VCRs is unsteady (well, junk) at times. The
condition of the tape can also result in a degraded/unstable signal.
What you need is a image stabilizer or TBC (TimeBaseCorrector).
I use an earlier model of the Sima SCC unit (now replaced by the
SCC-2):

regenerates the sync and colorburst info (and I see that the SCC-2
supports both PAL and NTSC - earlier models were NTSC only). A
pleasant side effect of a stabilizer/TBC is that it strips out the
macrovision crud that can also confuse capture cards. You can also
adjust the color/hue/contrast/sharpness/brightness for those tapes that
are in very bad condition.
TBCs can be found at BH Photo:
http://www.bhphotovideo.com/
put TBC into the search box and you'll get ~4 pages of equipment. Some
of which is VERY expensive, but some is more reasonable - you can get
a single channel TBC for $290 or so.
Cheers,
Steven Schultz
