It's probably not your setup. Roku doesn't support Flash, so I have to use the HTML5 iPhone/iPad versions of JustinTV's streams (which are of "mobile" quality). I can only display what they give me, and the quality that you saw is usually the best that they provide. What you see is what you get.
However, JustinTV (somewhat arbitrarily) also provides 720p HTML5 streams to a small number of popular channels in their "Gaming" category. The "Giant Bomb Live!" channel is one of those specific hand-selected channels, and those streams always look great on the Roku. Unfortunately, this is the only Whiskey Media-related JustinTV channel that offers high-quality video streams. If you ever see "Giant Bomb Live!" broadcasting live on the Roku, check it out.
Whiskey Media has said that they're dropping JustinTV in favor of Amazon at some point, so this will all be moot in the future. If Amazon provides HTML5-compatible streams, then they will also be supported in the Whiskey Media Roku channel.
If it's Tanya, then why keep it a secret at all? It's not like she's a fan favorite, or an all-time classic character. It just seems like if they make a big reveal out of Tanya, then it would be kind of anti-climactic.
She's still probably the best bet at this point, but I would still be surprised/disappointed if it was her.
I'm changing my own guess from Tremor to Cyber Shao-Kahn.
@snide: The Roku channel uses these exact feeds. I need a way to limit+offset the results, so that users can press the "More..." button to get older videos (especially relevant for Endurance Runs).
If you guys update the feeds, then I can finally pull the Roku channel out of beta, and put it into the public Roku Channel Store. I only need the preview images to be added to the feed, and the High/Low quality feeds to be unlocked for non-subscribers. Then we can actually release the thing!
Wrestling would be perfect for a Whiskey Media style wiki.
Dave said on his call-in show that they were considering it, but were afraid to get sued by Vince. There are plenty of other wrestling sites that don't get sued though, so I'm sure they could figure it out if they tried. Make it happen!
