Sorry, but it just seemed like the problem in the last thread hadn't yet been fixed. Here's the requested info:
Firmware version and build number: Firmware is version 6.1 build 5610
Channel(s): Seems to be primarily Vudu in HDX quality and Netflix in HD, though I saw a bit of it on Amazon HD, and switching Vudu to HD seemed to make it glitch less often and I did not see any at all when switching to SD. I checked some trailers on Blockbuster and they glitched a bit too, but Vudu and Netflix seem to be the worst. It definitely does NOT do this on any of the interface screens, only when playing video.
Have you rebooted? (If not, try it) Yes, several times. I also let it stay unplugged for several hours and cool down, but that did not help.
Have you deleted, rebooted, and re-added the channel? (If not, try it) Yes, for both Vudu and Netflix- had to re-register my accounts to get them back.
Can you upload a short video of the issue to YouTube or Dropbox (or similar service) so we can see what you're seeing? I'll try to get a video of it, my camera isn't too great though.
What is your Roku serial number? 1XE410015931
Please include ISP, router make/model, connection type (wifi/ethernet), connection to the TV (HDMI etc), peripheral make/models that are between the Roku and the TV, etc.
ISP is AT&T, Router is 2Wire 3600HGV, connection is wifi (only kind the Roku 1 accepts), and the Roku is connected via HDMI to a Pioneer VSX-23TXH receiver which is then connected to the TV's HDMI input. I checked the picture going straight to the TV but that did not make any difference.
Thanks for your help on this, it only seems to have come up after the last firmware upgrade.
