1. I suggest 3.5" USB instead of e-sata HDD, if you don't want to replace it. It also facilitates migration to other Magic TV models.
2. You can go to Science Park to trade in the MTV5000 for MTV3800D or MTV8000D, list price minus $700.
3. Some SATA to IDE adaptors work, some do not - may cause hanging during recording or playback. It depends on your luck whether you get one that works stably.
