i have been searching the net for FREE concert dvd sources. I am finding a lot of cool stuff out there. i can convert pal to ntsc.  
Been using
tapercity,eztorrent,hungercity websites so far. i tend to burn only quality stuff.
heres a few of what i found. ps- any rockplast shows are usually incredibly good quality
csny- wembley 74
warren haynes-07
elvis costello-78
dead-89
lots of clapton
led zep
mccartney
clapton and winwood
so if you know of any other sites- much appreciated

Get a job!  lol
 
Bill, tgo

Here's my favorite if you haven't come across this one yet.  
Once you register you are able to search their live concert community (video and audio).  
No upload or ratio requirements.

i just found a free download of return to forever from miami 08. stanley wails on his alembic!!!!

quality is excellent= i dont think hes playing dragons breath- but its hard to tell since i havent seen it on my big tv yet

say what you will- i download through bit torent which allows me to download as many as 20 files at one time. after download i review the files for quality and then decide whether to burn them or not.
this list is all really good quality or better.
