[QUOTE="mm1352000, post: 1107017, member: 82144"] Ahh, that could introduce its own compatibility issues. Well, stream bandwidth is variable from channel to channel. In general a single TV/video stream is usually anywhere from around 2 Mb/s (0.25 MB/s) up to 16 Mb/s (2 MB/s). However, when you tune a channel TV Server receives the full transport stream for the transponder/multiplex/transmitter. So, you need to be thinking about the bandwidth of that full TS... which for your provider with 64 QAM and symbol rate 6900 ks/s is approximately 40 Mb/s (5 MB/s). Multiply that by 3 for the 3 active tuners and you have 120 Mb/s (15 MB/s). Consider also the HDD bandwidth if the USB HDD is also being used for timeshifting (3 x 7 Mb/s???) or other things... In theory that shouldn't be too much even for USB 2 (limit 480 Mb/s)... but theory does not always work out in practise. [/QUOTE]
