After spending many nights searching these forums, and trying many of the suggestions, i still have a couple of issues preventing my HTPC being a 'dream machine', and hope someone can point me as to where my problems lie. I am very happy with the win7 GUI and love the usability and wife friendly ease, but live tv is just substandard. I do have it to a stage where it is watchable, however seems to be dropping frames, slight stutter occasonaly and glitching. I do not know if it is a hardware or driver issue, but please find below my HTPC specs, and the remedies tried upto now, and the results that have been reached. Lian Li C39 Case, Asus M4A785G HTPC Mobo, (using only onboard GPU) AMD Phenom II 705e Tri core @ Stock 2.5ghz, 4 Gb Ram Crucial ballistix 1066 Ram (4 x 1gb) @ 2.2v, lite on Blu-ray drive, 120gb western digital sata II drive (system), 640gb western digital green sata II (data) Kworld dual tuner PE355T (DVB-T). Windows 7 home premium currently 32bit. HTPC ouput via HDMI to 42LG7000 tv via Sony AV receiver SDR800DH. I have tried the following and received the results as noted.Re-installed Windows 7 32 bit and 64 bit. - Differences are negligible.Changed dedicated GPU ram in bios from auto to 512 - made live tv from unwatchable to almost watchable.MB Bios is upto dateKworls tuners are upto date - from Kworld global site - not microsoft.Changed voltage on memory from stock 1.8v to recommended 2.2v - generally improved system.Tried latest 9.12 ATI CCC - caused havoc.Latest GPU drivers installed - using windowes update facility.ATI CCC version 9.8 - only version i can get anything near to live TV working.TMT3 Platinum, as Powerdvd 8 that bundled with Bluray drive was poor by comparison.Any further help will be greatly appreciated, i feel i am at my wits end. I do not really want to start with registry hacks etc, as i hoped the spec above would be ample for my needs which are, live tv, pvr, music, watching blu-ray's, iplayer, tv on demand etc. If further specs are needed, please ask.
