Watching Star Cricket HD. Sound is great in 5.1, however picture is again much inferior than Dish HD. Seems TS do not wish to allocate bandwidth like in Dish HD to present less compromised picture and sound.
Again, sound quality is far superior on Dish HD confirming my assumption that these HD channels seems to also provide PCM Stereo or less compressed stereo bitstream which is greatly improving the sound quality on Dish HD. Sounds of Drums and Music is FAR more prominent on Dish HD than the soft rumbles in TS+HD in DD5.1. I prefer the stereo better quality sound on Dish.
Overall I find TS is using Video bandwidth of 50 to 75% of what Dish is allocating to its Hindi Channels. Some of the English channels are at par or superior on TS. Similarly Dish has excellent quality sound on Hindi channels and on some English channels (other than upscaled) sound is bit inferior to TS.
However on HD channels below is my finding:
TS use about 75% of the bandwidth than Dish for Video making Dish HD about 20 to 30% superior in PQ (Excellent details with hardly any blockiness). Audio bandwidth might be about 25% more on TS to accommodate DD5.1 sound, however as Dish uses 2.0 AAC, it sounds FAR superior and converted 5.1 effect is MUCH richer in quality and inferior in surround effect. This makes me prefer Dish HD to TS. However, as only TS has PVR function, might have to keep both
