Update-
Today I tried few original DVDs played from HTPC-
Armageddon, Fantastic4, Dostana, Gajani, Sing is King
To my surprise,7300 was doing much better upscaling than DVDp /BDp which I saw while searching for my TV.I have seen SONY BDP + Sony LCD playing DVDs.I can certainly say 7300 is doing far far better than DVDP/BDP upscaling as no artifacts visible, PQ looks 90% closer to BDrip with good colours,sharpness(compared with I m d legend mkv)as it its originally 1080p.
Only few jaggies as 5609 has 5ms response time with 60 Hz freq.
This is even present with 1080p clips.(Its LCD & not Plasma
)
I m trying to get BD-rom & BD disc from US,lets see.I dropped down idea of getting Pany BD-80.
I can say ,those who want all in one solution, go for proper
HTPC which will have a lot optionc.
