Re: [GnomeMeeting-list] Newbie UPDATE: slow video

[Jeff Mills <piggie optushome com au>]

Hi all.
For the record, I have had many of the same problems as Paul.
Although I havent tested it again recently simply because of bandwidth issues 
(most of my connections need to be to modem users), when I tested on my local 
LAN, I was having alot of these issues. GM locks, bad blocky pictures etc.
I think that oh323 and pwlib still have a ways to go. The software is all 
still under development. I would like to test GM to GM, but I dont have 
another Linux box to test it unfortunately.
I'm using Mandrake 8.1.
