Welcome to the forum :).
Unfortunately, at the moment there doesn’t appear to be a firmware update which enables DL recording on the 3355.
For your other question, if you mean the facility of ‘flexible record’ (make recording in best possible quality with amount of free space available), then I’m afraid the answer is again ‘no’. There are hardly any Philips models which have flexible record (DVDR72 does, I think).
Despite the non-availability of the DL and FR functions, you could consider to upgrade the firmware if your version is earlier than this one from the Philips site .
