I bought the 805 in good faith based on reviews and features. My unit came with 1.05 but I was able to apply the DSP update and the 1.08 update.
Even with the updates, some remaining problems still exist:
1. E2PROM error (not for all users, but seems a decent percentage)
2. Inability of the receiver to pass non-standard resolutions over HDMI. Not only is the receiver limited to standard resolutions (1080i/p, 720p, 480i/p), it is limited to certain timings. One DVI port on my TV has different 1080p EDID timings than another port. Both ports accept 1080p, but the receiver will only send through a signal to one of the ports. Sending a resolution from a PC such as 1280x1024 does not work at all.
3. HDMI/HDCP syncronisation problems persist when connecting the receiver to an HDMI input. If I wanted to watch HDMI input 1, I would switch to IN 1, switch to an input with an inactive source, and switch back to IN 1 to get a signal lock. Powering the TV off/on may or may not work. Getting flashes of static, green, purple, etc would persist until the lock.
4. When connecting to a DVI input, the receiver has serious problems with 1080i. It seems that the receiver will pass a 1080i signal still but corrupts this part of the EDID so the source thinks that the display is not 1080i capable. 1080p still works fine.
Some of these isssues are likely isolated to my setup, but I am sure other issues exist with differing setups. In an industry where virtually every DVD player, HD-DVD player, Blu-ray player, TV, game console, etc receive multiple updates to fix HDMI compatibility issues, Onkyo has not released a single HDMI update.
The updates that were eventually leaked are unsupported, unacknowledged, and a hassle to download and install.

Thanks for the information, jruser. I see there are still some lingering issues for some configurations, unfortunately. Luckily I have not encountered any of the issue you've mentioned (all my gear is HDMI 1.1 minimum) with my TX-SR805.
However, I have encountered one issue: I have a SNES around for some old-school gaming for myself and my nephews, and it is connected via an S-Video cable to the receiver; the receiver connects to my TV via HDMI. The signal from the SNES is garbled via that path (it's there but it moves around) and is unwatchable. However, when I use the S-Video monitor output of the receiver the picture is stable and crisp. I cannot determine what the cause is.
On the plus side, it is the only receiver I've found with the guts to properly drive my inefficient 4ohm Onix Reference 1 monitors (without a hint of strain).
