Many thanks to all who sent me info on IR remote controls for VCRs. 
Here's a summary of the information I got:

brianr@tekig1.pen.tek.com (Brian Rhodefer) says that Radio Shack makes an
IR receiver module that could be used - it contains a phototransistor,
tuned amplifier, and demodulator that operates at 40 kHz.

bbs.haymore@tsoft.net (Ed Haymore) says that his friend was experimenting
with this sort of thing and most VCRs used a carrier frequency of about 38
kHz, digital on-off-keying modulation.

jmorriso@ee.ubc.ca (John Paul Morrison) says that most VCRs use digital
pulses of 40 kHz carrier.

So based on this information, it sounds like a frequency of 40 kHz is
pretty standard as a carrier.  So what I plan to do is use a 567 tone
decoder to demodulate the signal, a 555 to modulate, when sampling just
time-stamp the edges of the modulation and play that back into the 555 at
40 kHz.  This is very short-range, so it doesn't matter if the transmit
frequency is a bit off and is just on the edge of the VCR receiver's passband.

Again, many thanks to all who tried to help - I'm new to Usenet and you've
all given me a warm welcome.
