Digital Concert Hall

Can anyone give me advice on using this service (http://www.digitalconcerthall.com)?

I am trying to use it with 64-bit XP system connected directly to ADSL modem via ethernet over 4mbps line, but experience occasional jitter which makes watching unpleasant. Any suggestions?

My guess is that your account is being shaped badly or that you're sitting on a congested exchange.

What ADSL account do you have? Shaped uncapped from like Axxess/OpenWeb/Afrihost?

Secondly, what times are you trying to watch from that site? eg. 20:00 - 22:00 ?

Lastly, could you perhaps post a trace route to that site? To do this, open up Command Prompt and run: tracert www.digitalconcerthall.com
I kept on getting " * * * Request timed out." at hop 15+, since they're blocking ICMP (Ping) packets, so don't worry about that because you'll be getting the same kind of thing.

I have an Afrigamer (4mbps 35GB unshaped) account with Afrihost (I called them this morning to confirm). I've tried at various times - definitely better after 20:00, but still get the occasional hiccup. They apparently use use Adobe dynamic streaming - is there any way at all to cache on my end? Or any other way to improve performance?

ping/tracert both give continuous timeouts

ping/tracert will give timeouts since ICMP packets are blocked on that host. I specifically asked for a trace route, because I'm interested in the first couple of hops, which could show us whether the Telkom exchange is congested or just if you have a slow international connection.

tracert just gives " * * * Request timed out" continuously

I am watching now and get breaks of 10+ secs from time to time

try a pingtest (www.pingtest.net) and a speedtest (www.speedtest.net) to UK and/or Germany and a reference test to a server closest to you. There may be speed degradation occurring on international traffic. Post results.

Just paste the tracert results here. There is definitely something wrong or you're blocking stuff with a firewall if it is giving you that "Request timed out" on every single hop.

Update: Checked the ADSL modem and found firewall enabled, so I disabled it..

Question is: am I being too optimistic expecting being able to watch live video for www.digitalconcerthall.com without any hiccups?

Is the content HD (720p or 1080p)? If so you will likely have issues; 360p or 480p shouldn't be a problem; The speeds and ping seem good.
