The Oppo will also accept USB input which can then be fed on to HD621 > V6 which may open up other possibilities .
~M~
Unfortunately, this is limited to a single 2GB FAT partition IIRC. It would be fantastic to be able to connect it to a RAID array.
I did A/B video comparisons between the Oppo and the Seagate Theater+ Both units are fed through the HD621 and I can say with certainty that on a 50" 1080p Elite Kuro there is no difference in video. It is exceptional on both players. Mind you the Theater+ is $129 sans HD/NAS.
(The Theater+ uses a RealTek chipset and while it may not in theory extract as well as Anchor Bay it is indistinguishable at the 50" screen size; i additionally paused a few movies on both players and inspected the pixels.)
The Theater+ is cat6'ed to a RAID 5 with 8T of data and on 98% of Bluray 1080p rips there is never a dropout or stutter. 1080p MKV files play flawlessly as do AVI etc. Subtitles work flawlessly. I have hardly used my Oppo since going this route.
I am awaiting the new widget-based Intel media chip powered Yuixx media player to replace my Theater+, which should be incredible.
I hope this helps someone.
PS the Theater+ accepts any USB drive in any capacity formatted in various non-FAT partitions; in fact the Movie organization works better in USB drives than the NAS, but NAS fw update is immanent.
PPS SOMEONE PLEASE REPORT BACK ASAP ON THE 861V6 AS FED THROUGH A HD621 INTO DSP SPEAKERS!
