I have just upgraded my V2 box to 160Gb using the recommended Maxtor 160Gb drive. This is the same drive used by Sky in their 160 box. Almost immediately I have experienced the sound drop outs on Dolby Digital channels (Sky movies 1 & 2) and Disney Channel. This problem existed before (and after) the latest firmware upgrade. I selected this drive as I thought it would be the quietest (doesn't leave the fan permanently on). It would appear that this drive is the root cause of the sound problems. Can anyone confirm this and does anyone have an alternative drive that a) does not make the fan run permamenantly and b) does not cause a sound issue?
