I would get the DVE, the audio section is much better than the Avia, IMO. I have the newer DVE and Avia and am waiting for Avia II. DVE HD content is in 1080P/24, 720P/24 or 720P/60 and has Dolby true HD and Dolby Digital Plus. I do not have a HD player yet so I can not comment on this portion of the dvd, but the SD is quite good and informative and as I said the Audio section is much better than Avia's. DVE has full spectrum sweeps and 15hz-300hz buzz rattle tests. The Avia is a little too basic, IMO.
