If you haven't tried it, you don't really know... They have a free version...
It might of been fine for you but you werent strteaming 720pmv at all on a 1mbps connection! people struggle to stream anything resembling HD via 6mb connections!

"Good quality 720p HD takes at least 12Mbps, and 15Mbps is a more reasonable
minimum. Good quality 1080i takes at least 15Mbps, and even 28Mbps isn't
enough to eliminate all artifacts (based on D-Theater tape bitrates and
quality)."

which is of course irrelevant as the airvideo server would have been massively downgrading the video before it sent it, it doesnt matter what it was in on the PC.

Also most 3g speeds state faster than 1mbps but NONE of them get close to averaging it! here is a table from computerworlds large article on 3G

3G Networks -- Test Results
AT&T LaptopConnect Sprint Mobile Broadband Verizon BroadBandAccess
Peak download speed* 1.6Mbit/sec. 1.2Mbit/sec. 1.3Mbit/sec.
Average download speed* 755Kbit/sec. 494Kbit/sec. 592Kbit/sec.
Average upload speed* 484Kbit/sec. 294Kbit/sec. 232Kbit/sec.
Connection time** 3.0 seconds 3.7 seconds 5.6 seconds
Time to load Web page** .228 seconds .224 seconds .230 seconds
Battery life lowered by** 40 minutes 1 hour 20 minutes

there is no point trying it as I dont have guarenteed wifi access on a plain or holiday so Im just going to put my video on a memory stick.
