OK, I have a first-seen situation here... I set up BOINC with SETI on a new host of mine that's connected through a 3G WiFi hotspot. The host has not been able to download any work, have a look at its link above.

All tasks fail download with error <error_code>-200 (wrong size)</error_code>, but that error is on ap_601.jpg image file and I've set the BOINC client to skip image file verification. Have a look at any unit result Stderr output.

I know the internet provider is compressing images, but why would it not work with image verification set to off? Any hints?

You mean you set locally 'Skip image file verification'?:
http://boinc.berkeley.edu/wiki/Local_preferences#Network_usage

Check in global_prefs_override.xml for this line:
<dont_verify_images>1</dont_verify_images>

I don't know "why would it not work with image verification set to off" if the above is set at 1


You can (temporarily) avoid you ISP for re-compressing images by using VPN
(you ISP will not be able to see or change anything of your communication)
You only need one Download to happen for a task type.

Get SecurityKISS (free for 300 MB/day, >10 servers to choose, work OK with SETI@home servers):
http://www.securitykiss.com/resources/download/windows/

(I use it from time to time, it do not install always-running services like e.g. Hotspot Shield)

I will check later the xml file for the <dont_verify_images> flag, the host is a bit remote.

However, I don't get it; Just wiped BOINC and reinstalled from scratch. I personally observed the download of three 8-MB astropulse work units, there was real incoming traffic. BEFORE the downloads completed (while still active on BOINC Manager's "transfers" tab), ALL THREE were deemed as "error while downloading" under Manager's "tasks" tab. Why's that? Just because a project image failed to download correctly? I really don't get this behavior, never seen it before.

Here's the log file of the transfer I am referring to:

Tried resetting the project a second time... This time made sure that the <dont_verify_images> flag was set. Same results. What I noticed was though, that all downloads started as expected (work units, clients, extra files, images) and nothing was failing until a .jpg was downloaded. At the same time the .jpg download failed, all work units downloads failed as well. The rest downloads completed successfully. Looks like this is a BOINC issue, I will move my thread over there, as well...
