Thanks. Yes, I realized that just after I hit "send" :(
Anyway, if I use the following, it works great:
tcpreplay -i eth0 -R -w cooked2eth.cap
-2 00,00,00,00,00,00, 00,00,00,00,00,00,08,00 cooked.cap
Thanks for the suggestion!

Using -2 specifies the *entire* layer two header (all 14 bytes for
ethernet). You've only specified the first 6 bytes, so the IP header
is starting at byte offset 7.
