Mario Bava directed the sequence with Polyphemus, the Cyclops, and Piero Schivazappa directed the sequence with the Trojan Horse.
When the bow of Ulysses is taken form the storage room it is clearly strung. Bows have to be stored unstrung or they lose their strength over time (and this one is said to have not been touched for 20 years). As a result the movie deviates from the epic in the essential part that in the epic the bow is useless to the suitors because they are unable to string it (either due to lack of strength or not knowing that a composite bow is strung backwards). The movie on the other hand shows the suitors (rather unconvincingly) unable to simply draw the bow.
The ElleU Multimedia (Rome, Italy) DVD release, on 2 discs, eliminates the initial and final titles of each of the eight parts of the original TV movie (except for the initial titles of the first and for the final titles of the last one), thus presenting the whole series as a single movie. On the contrary, the VHS release, on 3 cassettes, maintains the titles of every single part. This could be the reason for the different running time, leading to the conclusion that the DVD release is not cut.
