Just to say I have the AVR600 with the BDP300 and they both work perfectly together. However I did have 3 BDP100's before and they all failed to work properly for one reason or another over a 15 month period so I upgraded to the BDP300. The load speeds are brilliant, really quick and the response from the remote excellent, the BDP300 does appear to be a totally different monster with different software and now appears to be a great investment after testing my patience to an extreme!
