Hi, I have 3 identical machines (pvr-9300T) purchased recentlty. They are all working perfectly - should I resist trying to do a downloaded software file update and leave well alone and just wait for a OTA auto update? Have read some horror stories about people buying these RS-232 gismos that do not work and then find the attempted upgrade has failed and corrupted their system, and am very very reluctant to fix something that ain't broke. Machine 1. Rev 1.0/ver 1.00.26/loader ver a4.37/sys id 3023.0000/update date July 7, 2011. M/c 2. Rev 1.0/ ver 1.00.24/ Loader ver a 4.39./sys id 3023.0000/ Update date Jan 18, 2011. M/c 3. Rev 1.0/ ver 1.00.24/ Loader ver a 4.39/ sys id 3023.0000/ Update date Jan 18, 2011. Have received OTA updates on m/c No.1 - but have not had the opportunity on No2 or No.3. Can I assume M/C No.1 is up to date (bearing in mind the loader version is only a 4.37)? or will this m/c need a fix as well? I have futher questions on this subject, but would like to take it in stages for simplicity. Advice and patience apppreciated as this is a bit over my head. Thank you. Jim.
