No success in search results for knowing differences between 4501, 4505/4506 tuners. DM 8000 user manual has no info on input symbol rate for DVB-S and DVB-S2. If anyone has info on these tuners specifications especially input symbol rate, please inform. I'm interested in knowing if DM 8000 built in twin tuners accept symbol rate of upto 45000 for DVB-S2 (8PSK), if not what will be the best tuner option for plug&play slots.

Thanks & Regards,
