BBC iPlayer Performance problems / question

$

Hello

I'm experiencing some performance/buffering issues with BBC iPlayer Plugin 1.2.9 and could use some advice. Recently (last few weeks?) I have found buffering issues when using "Listen Live" on BBC Radio Scotland. I can listen to radio for perhaps 5-10 minutes and then it'll stop; if I look at the SB3 screen it'll say Buffering 5% and it usually never advances beyond 5%. Sometimes it does advance, and the music will start again after 20 mins or so, but usually it does not and I have to choose Listen Live again.

When this happens, there is virtually no network traffic across my internet connection (8Mb downstream). Conversely, yesterday I was listening to a "staff picks" stream on the same SB3 at the same time as I was practically maxing out my internet connection with a 23GB binary download; the download was coming down at 825KB/s (almost full rate for my line) and yet the audio didn't skip a beat - in fact I forgot about my download at one point as I was listening to the music! So I do not believe this is a bandwidth issue.

I have the iPlayer plug settings at their default, the only thing I have changed is the overall "Radio Station Buffer Seconds" value, which is 30 seconds.

The SB software is the latest and is running on a Linux VM installed under Hyper-V; The VM has 2GB RAM and oodles of CPU.

Logitech Media Server Version: 7.7.2 - r33893 @ Wed Mar 14 05:46:46 PDT 2012
Hostname: music.123XXY.co.uk
Server IP Address: 192.168.1.60
Server HTTP Port Number: 9000
Operating system: Debian - EN - utf8
Platform Architecture: x86_64-linux
Perl Version: 5.14.2 - x86_64-linux-gnu-thread-multi
Database Version: DBD::SQLite 1.34_01 (sqlite 3.7.7.1)
Total Players Recognized: 3


Can anyone suggest any diagnostics or ways to alleviate this issue? I am not sure where the problem lies, but I do not think it's bandwidth. I only seem to get this issue with the iPlayer plugin.

Ping times for my connection to www.bbc.co.uk are around 28ms.

Many thanks



Jim
