I've got one of the 31.5" Vivos. They almost are the same as the AKAIs that the warehouse sell and I'm fairly certain they are the same hardware as the 32" Veons. Different looking firmware, outer shell and remote though. 3 HDMIs, 2 bottom entry, one left side. Headphone output, USB(bottom entry).
The picture quality is pretty decent, it has played most of the video files I've put thru it, 1080p MKVs, VOB files, full BR rips. Though it doesn't seamlessly span VOBs or support DVD menus, and I've had the occasional ungraceful crash, which requires you to turn off and on the TV. It can read both Fat32 and NTFS formatted drives.
Sound is ok for an LCD TV, it has downfiring speakers of a larger size than some other slim line TVs, so not quite so anaemic on the bass. Supports a good number of resolutions through the VGA port when plugged up to a computer. Haven't used the component or composite inputs so don't know if there are any problems with them. HDMI works fine.
Startup time is a bit slow, 5 secs before you get the logo, then maybe another 5 till you get the tuner. It has an independent analog and digital tuner, not that that matters to most people.
I did have one issue with the remote, but I think the battery holder might be a bit too tight and can hold the batteries off the circuit.
I haven't tried the PVR function yet, so can't comment on that.
All in all a lot of features for a bargain basement price. You might want to look at the Veon's instead, as they look nicer IMO (gloss look), psudeo-samsung remote layout and firmware. Also they come with a 3 year warranty. Also the are the same price of $399 at the moment
