It works great to decode the channels in question in the UK, but the 
decoder still deadlocks after a couple of hours. I don't think it's the 
size video buffer on its own. What else could have changed, especially on 
30th August 2002 in the firmware concerning buffer handling which appears 
to make it lock up in continuous replay / transfer mode?

It would be great if the firmware was modular on loading - i.e. if a 
certain parameter could be passed which allocated memory for feature x 
(like timeshifting on same card) etc. or disabled that feature and instead 
allocated teh memory to vid mem or osd . This would also be helpful to 
debug this problem to see which new feature or "cleanup" to make space for 
new features introduced the stability issue on replay.
