I wouldn't entirely agree with you. I have done side by side comparison and below is my observation:
1. All the DD Direct+ channels look much better on Dish TV and are essentially free when most of the other operators don't have them all and operators like TS do not give ANY for free and that too at much reduced quality.
2. Several GEC channels look and sound better on Dish TV
3. Upscaling on Dish HD box is much better then likes of TS+HD I am currently using. As Dish HD do not use deblocking, it actually enhance the resolution of SD channels while TS blurs blocky images and hence degrades the resolution atleast on those areas - makes the picture look more like out of focus images! I used to have tough time focusing the images when I got it initially. Might be bad for your eyes!
4. Audio is usually okay on Dish TV especially when I took the optical output as otherwise on TS+HD its HEAVILY DYNAMIC RANGE COMPRESSED making it very synthetic, lifeless and sometimes inaudible voices, background sound or music.
5. Audio on HD channels on Dish HD still seems to be Stereo, however as there is no DRC, it usually sound better than what TS does on Star Cricket, Discovery and Nat Geo. For me, audio on these channels is VERY DISTURBING as TS is butchering it heavily without any purpose when they should only pass original audio.
6. TS keeps playing with Interlacing flag previously on Max HD and now on Star Cricket HD - Infact, they have SCREWED the flag since past several days and have gone to sleep!!! Absolutely unacceptable. On the contrary, HD channels look much better consistently on Dish HD without such issues.
I have referred TS for comparison as most of us think its the best and also as I am currently on TS+HD hoping for it to improve through regular escalations. Nevertheless, now I have decided to take them to the consumer court for not resolving the straight forward issues I have reported to their CEO and COO. They have chosen to play deaf and dumb instead of disabling all sorts of audio processing and fixing video issues like on Star Cricket HD since past almost a week now which is only a SINGLE SETTING to fix.
If they just read these lines, and have the minimal understanding of interlacing flags on their MPEG4 encoders, they can fix it within seconds! I am not putting any complaint which they could not resolve in seconds! I am neither asking them to improve quality or add channels, just asking them to disable audio processing and fix intermittent settings related issues if they come like now.

LyngSat for TP SR which is proportionate to their bandwidth.
