I love flash TV, also there's LiveTV, TV.com, TVU. Guys lets not bash each other, if You personally don't like Flash TV or any kind of app then that's cool, but some of us like using these TV apps. I have to say, some channels don't work, or something app wise ain't working, but that's ok with us. It FREE except, TVU which is like $5 a year. I use it to watch dragonball z, they have a all DMZ channel, a all Family Guy channel, and All South Park channel. I say its worth the $5 a year ToMe and it looks good on 3g.
If you go lurk over on xda you will find the way in the development section for the evo. I'm on my phone so I can't look and provide a link. Some rom's have the fix built in, too. I don't have the fix done so idk how complicated it is.
