I recently rebuilt my HTPC, and had previously used Arcsoft TMT3. It worked really well for me, and I really liked the MCE integration. On the new HTPC I'm still using WIndows 7, but I upgraded to TMT6, and it has been very disappointing. For one thing, it really slows down my boot times (a well-documented issue), but it's also responds verly slowly during playback to pause/FFW/RW buttons, which TMT3 did just fine before.
So I'm looking to move away from Arcosft, but was wondering what others were using for Blu-ray disc playback. I know of PowerDVD 13 and WinDVD (version #?). Also why did you choose that application over the others?
I'm looking for streamlined MCE integration (insert a disk, and it just starts playing), and full blu-ray playback capability (menus, BD-Java, etc.). I'm also outputting analog audio, so any app that doesn't down-sample analog would be preferred (I know arcosft TMT3 down-sampled, but it didn't seem to affect the sound that significantly).
