Both Avia & DVE would work more than adequately for your use. I think the Avia disc is more expensive than the DVE disc. But I bought the Avia disc so long ago I don't recall exactly what it cost.
I never cared for the Avia disc, but I was already used to Video Essentials. I haven't put DVE in the player yet, so I don't know if it's any different useage wise than Video Essentials is.
And yeah, if you went with DVE, you'd want the NTSC version.
