Hi Brianzion,
Changing the buffer time in registry did not fix the problem, but following instructions from that same website I increased the "skip interval of live and recorded TV". This seems to have had some effect because I have been pausing/unpausing and skipping backwards and forwards without the crash problem occurring. Not sure why this change would fix the problem but it seems to have done the trick.
Thank you very very much for pointing me to that website, I am much obliged.
Lysander.
