Am I correct in believing that with the right hardware VDPAU is supported in 810, and additionally mkv files play without the green garbage/blocks?
I'm unhappy to report that it looks like my external USB (old one, not new one), may be corrupted to the point of no return. 750G drive, around 600G of data, and 2 days of fsck and still going strong. At one point it was fixed enough that LMCE automounted it (ugh, fsck was still running), so I have removed it as a device to avoid that. In any event, if it is as corrupted as it appears, I'm looking at re-ripping/converting over 300 DVDs that were on that drive. Ugh.
However, in looking for a bright spot, if VDPAU and mkv are both working out of the box in 810 I will probably rip/convert them to VDPAU compatible H.264 mkv files. If not, I may just bite the bullet, buy more disk, and rip the full DVDs as ISOs. I just hate using more than double the space and being forced to navigate the DVD menus for no perceptible difference in quality.
