I'd say that the largest problem with the OT from a technical plot point of view is the idea that the Millennium Falcon, without hyperdrive, manages to locate and fly to Lando's mining operation...
Alright, here's the best I can come up with:
The Anoat system is a neighboring star system to the Hoth system. They are rather close together in galactic terms, probably much closer than the average two systems. (Such as the Sun and Proxima Centauri).
The Falcon limped its way there without a hyperdrive over a significant period of time. Weeks or even months. Even at sublight, over time the Falcon is able to accelerate up to speeds that can make this journey.
Meanwhile, Luke travels to Dagobah in a far shorter period of time (hours to days) and spends the interval training with Yoda. He arrives at Cloud City later on through the benefits of traveling again through hyperspace.
Also, it's pretty strongly inferred through in films that the Falcon would have no trouble outrunning a Star Destroyer in a straight drag race, but things become complicated when you factor the Destroyer's turbolasers into the mix. The Falcon has to dedicate vast amounts of available power to rear deflector shields in order to withstand the blasts from the bigger ship. Because of this, only a fraction of the Falcon's potential speed is available to flee with.
As far as meeting Lando...
It's not called "Solo's luck" for nothing.
