Especially complicated command like CX2341X_ENC_STOP_CAPTURE takes much more time than 10 ms. Increase the timeout to 1 second, just as ivtv does (the cx88-blackbird has the same IP core for MPEG compression as ivtv). This solves a nasty issue where STOP_CAPTURE would timeout and the mailbox is left in a busy state, making it impossible to start streaming a second time without reloading the driver first.
