Pretty simple, output file goes to C:\\Users\\*User Name*\\Documents\\CyberLink\\PowerDirector\\9.0 I think.
One last pitch...
PowerDirector is a CyberLink product (also author of PowerDVD). CyberLink is a very "intrusive" software vendor, but if PowerDirector works for your needs be my guest.
However, technically speaking, M2TS are "wrappers" that can contain underlying transport streams encoded with different codecs. If you have a WTV file (and WTV is a "wrapper" as well) that was recorded via Windows Media Center from an OTA or copy-freely cable channel, the underlying compression codec used was MPEG-2. So converting WTV/MPEG-2 to M2TS/MPEG-2 is not really a conversion/transcoding as such, but really just changing the "wrapper". Apparently your PS3 can't handle WTV wrapper but can handle M2TS wrapper, even though the underlying data stream in both files is compressed using MPEG-2.
So, any program which can "re-wrap" the transport stream WITHOUT RE-ENCODING TO ANOTHER COMPRESSION will be "extremely fast". I'm sure this is what is happening with PowerDirector and your experimental WTV file of 40 minutes that converted to M2TS in 5 minutes. It probably was one of these "fast copy" re-wrap situations, with the output M2TS result still using MPEG-2 compression.
In passing, if you'd specified "M2TS - H.264" as your output (with the compression codec used being H.264 instead of MPEG-2) then MAJOR TRANSCODING would have been required and a VERY LONG and 100% CPU BOUND process would have ensued, to produce that M2TS/H.264 result.
Nevertheless, converting WTV/MPEG-2 to M2TS/MPEG-2 is really just a "fast copy" to re-wrap it.
Ok, by comparison, VideoRedo TV Suite v4 does EXACTLY THE SAME THING... it can "re-wrap" a native WTV/MPEG-2 input file into an output M2TS/MPEG-2 file using what it calls "fast frame copy" since it knows no major transcoding is required.
I just ran a test of my own, using an input WTV/MPEG-2 recording (from an ABC "The Bachelor" OTA recording using WMC and my ATI TV Wonder 650 PCI tuner card) that was 2 hours in length (9.7GB), converting it to M2TS/MPEG-2 using VideoRedo:
Total time to convert 2 hour input file: 2 minutes 6 seconds.
I would say that is CONSIDERABLY faster using VideoRedo (about 1.04 seconds per minute of input) than your test, which used PowerDirector and converted a 40 minute input file in 5 minutes (about 7.5 seconds per minute of input).
Again... ZERO loss of quality. WTV/MPEG-2 is identical to M2TS/MPEG-2, digitally, inside in the transport stream. No re-compression at all. Viewing WTV/MPEG-2 is identical to a "fast frame copy" into M2TS/MPEG-2, which is identical to the original OTA transport stream which was MPEG-2. Visually, these are all identical... assuming a player that can accept any of these file formats. MPEG-2 is MPEG-2.
|But i do have a diffrent question, How do i make windows media center change the channel for recordings?
If you're using WMC, you need to give us much more information on your setup. What is your TV tuner card, for example?
WMC if properly set up has its own Electronic Program Guide so that you can conveniently pick programs or series to watch/record, the ability to watch/record live TV (like a DVR), playback recordings, etc.
Your question of "how do I change channels with WMC" is a very basic one. You can use the onscreen Guide, which you navigate as you'd expect with keyboard or mouse controls or a WMC remote (to an IR receiver connected via USB), or just directly through the proper keyboard shortcuts or remote buttons to up/down channel.
