Gerunds
A gerund can be one word (driving) or part of a longer phrase, with an adverb (driving slowly), a prepositional phrase (driving in traffic), or an object (driving a big car).

Infinitive
 An infinitive can be to words (to drive) or part of a longer phrase with an adverb (to drive slowly), a prepositional phrase  (to drive in traffic), or an object (to drive a big car)

LOVE, LIKE, HATE AND PREFER THE INFINITIVE AND GERUND ARE SIMILAR MEANING. 
HOWEVER, SOMETIMES IT IS MORE COMMON TO USE AN INFINITIVE TO TALK ABOUT AN ACTIVITY AT A SPECIFIC TIME AND A GERUND TO TALK ABOUT AN ACTIVITY IN GENERAL.

I LIKE SWIMMING AND BOATING.(ROUTINE, IN GENERAL)

AFTER FORGET, REMEMBER, REGRET AND STOP THE INFINITIVE REFER AN ACTION THAT HAPPENS AFTER ACTION OF THE MAIN VERB. GERUND REFERS TO AN ACTION THAT HAPPENED BEFORE THE ACTION OF THE MAIN VERB.

I REMEMBERED TO MAIL THE LETTER.(I REMEMBERED THE LETTER. THEN I MAILED IT)

I REMEMBERED THE MAILING THE LETTER.(I MAILED THE LETTER. LATER I REMEMBERED DOING IT)   

FORGET IS USED WITH INFINITIVE, WITH GERUND, IT OCCURS MOSTLY IN SENTENCES WITH WILL NEVER.

I FORGOT TO PAY MY TELEPHONE.(I FORGOT SO I DIDN'T PAY THE BILL)
I WILL NEVER FORGET LIVING IN ECUADOR.(I LIVED THERE. NOW I'LL NEVER FORGET IT)  

REGRET CAN TAKE EITHER AN INFINITIVE OR GERUND WITH VERB SUCH AS INFORM, TELL, SAID AND ANNOUNCE.

I REGRET TO INFORM YOU THAT I'M LEAVING.(I FEEL REGRET. THEN I INFORM YOU)
I REGRET INFORMING YOU THAT I'M LEAVING.(I INFORMED YOU. NOW I REGRET IT)

AFTER TRY, INFINITIVE AND GERUND ARE SIMILAR IN THE MEANING.

WHEN TRY IN IN THE PAST, THE INFINITIVE OFTEN IMPLIES THAT AN ACTION DID NOT OCCUR. THE GERUND IMPLIES THAT AN ACTION OCCURRED BUT MAY NOT HAVE BEEN SUCCESSFULL.
