question about various YouTube online recorders/converters

[jimdagys]

I am in China where Youtube is blocked. (Many websites like blogs, etc are blocked here. One can usually get around this problem by using a proxy, such as www.zend2.com, however, after trying many different proxies, I found that the proxies don't allow the Youtube streaming video protocol to go through.)
I wanted to get a few videos from Youtube and put them on my hard drive. After reading on this site, I found various free online Youtube online recorders/converters. I found that these online recorders/converters bypass the need for a proxy, so I can easily get the Youtube videos recorded on my hard drive as standard avi files. My question is about the comparison of 2 of these recorders. One that I tested is
http://vixy.net/
and the other is http://www.zamzar.com
I used both of them to record a short Youtube video. (By the way, fortunately I can get the urls for the Youtube videos in Google Video. That info is blocked on Youtube via proxy.) The vixy converter did the job much faster and the final file size was about one fourth as big as the zamar converter, which took three times as long to get the final result. About the image quality difference between the 2 converters, I am not sure. I am curious why the file size is so different between the 2 converters. I am wondering if someone can test both of the converters (on the same video file) and tell me which one do you think has a better image quality. I also found that the vixy converter did not work reliably on videos that are longer than 1 minute, but the zamar converter did a good job on videos that were 5 minutes long.
