I have a netbook with limited processing power. Some initial tests with replay of HD video were OK, but the video would occasionally skip a few frames. So, given the netbooks' limited processing power, it did quite well.
My tests were for a 1080i broadcast recorded as a WTV file by Windows 7 Media Center (recorded on a different, more powerful machine). Similar results were obtained for a DVR-MS file.
Replay was via Windows 7 MC and Windows 7 Media Player (no difference in response).
My question: What formats/codecs do the best for replay on Windows 7 machines with limited CPU and video chipset performance? What format variations should be tried to obtain the best visual/audio replay - is 720p less intense for replay than 1080i? What other formats/codecs might work better: H.264? Divx?
What other general suggestions (tweaks of hardware acceleration, etc) are recommended?
I recognize that netbooks aren't yet appropriate for HD video, per se, but what was surprising was how well the netbook did - just some choppiness, and occasional tiling, so it seems within reach that by using a different format/player it might work sufficiently well as a portable HD playback device.
- AMD Athlon Processor L110 1.2 GHz
- 2 GB RAM
- 32-bit Windows 7 Home Premium (upgraded from original Vista basic)
- ATI Radeon X1270 display adapter
Any other optimization recommendations (shut down certain services or programs, etc) would be helpful.
