What about ShortCall + LongPut to capture the dividend twice! Of course opening the positions much before ex-div.
Remember that the dividends (and interest rates) are already baked into the prices. So, you will receieve less money from your short call and you will pay more for your long put, and that net debit will be equal to the sum of dividend plus interest rates. In short: no arbitrage possible... That is, if I understood this whole put/call parity thing right
