yeah... I will look for some mpeg4 .TS files, just to be sure.
No, I don't use X1300 anymore, it's MSI 2600 XT 256MB GDDR4 w/8.401 (7.9) drivers that drives me nuts on mpeg4. Mpeg2 HD plays smooth with almost every driver/renderer combo though.
Now I've got me a 2 GB extra stick of DDR2, so I have 2.5 GB of RAM now. Only to discover it takes just a tidbit longer for DD or VLC (out of TS Reader chain) to crash than before, that's all. Looks like I need to clean out all the codecs again (some came with K-lite pack, and some said they are just bunch of crap for DVB). Judging from your config, apart from ATi MPEG Vid Dec which I believe is a native weird name for H.264 directshow filter, you use commercial Cyberlink 7.x (out of 7.3?) as a mpeg2 video filter and Sonic Cinemaster audio which I don't think is important at all.
As for playing HD mpeg4 files, the whole 64 pages of HD2x00 cards discussions at AVS Forum is full of it, but the main concern was with "old" drivers uncapable to accelerate mpeg2. Mpeg4 playback rarely if ever caused any concerns about hardware acceleration not turning on/greyed out, etc. Now everyone seems to find out how to resize overscans, color range, etc. Whereas what I'm experiencing is obviously a lack of hardware assistance in decoding HD mpeg4 live streams with much lighter bandwidth than any of HD/BR DVDs they usually test the card with.
Where's the DVBN sie? Come back, please..... Some f#cking hacker chosen a very bad moment to attack and deface site, within an hour after I installed my spank brand new MSI HD2600 XT. When it was alive, there were couple gurus there, plus Genpix himself who could help me.
BTW, I still can't get Cyberlink (New) (mpeg2 decoder in DD Video config not greyed out, and the only combination with both mpeg2 and mpeg4 decoders active is with ATI + ATI MPEG Vid Dec. Which doesn't work, drat!
upgraded from x1600 to 2600xt and lost HD playback

This is how my system looks after DVBDream loads + other apps that I usually have running (torrent, IE, Word). 968MB would have been very close to my old 1Gb limit. So the upgrade made a lot of sense for me.
Besides... memory is cheap now and it extends the life of your HD (less paging) and lowers your overall cpu load.
Also remember to change your pagefile. It is recommended that you have it set at 1.5 times the size of your memory to start... and 3 times as the maximum. At no point should your pagefile be smaller than your ram. This is something a lot of users forget to do after a memory upgrade.
I don't think that will solve your problem, but it will help your system run a little smoother.

well, it didn't solve my problem with smooth playing DN HD H.264 streams.
There's a chance that part of my problem stems from my desire to run my Mitsubishi 37" LCD TV via its VGA input (1920x1080p, with auto interleave - vector adaptive -- in CCC). It works just excellent, fluid, with obviously full hardware acceleration for HD mpeg2. I just hate HDMI (1080i) inputs, and poor (bob or weave) interleave schemes that TV set employs when it's not Sony Qualia model and just another piece with proud label "Full HD 1080p). Many other later models also are trying to put lots of crap in HDCP via DVI in HTPC configs, so if and when I decide to get me an HD/BR DVD drive for my PC, there might be some problems with HDCP non-compatibility. But in my config, I can expect them show up at only one end (HD DVD drive itself, solid evidence is AnyDVD solves any problems with that), and not at my TV end if I use VGA input only (and not DVI/HDMI).
Got rid of Cyberlink 7.3 because I still believe that better or tweaked ATi drivers/ATi mpeg decoders (out of AVIVO package) can provide complete engagement of 2600 XT hardware mpeg acceleration abilities also for mpeg4 in 1080p with vector adaptive interleave. Which is what I lack now. Your 3 Gig RAM rig still looks to me you still do it in software, somehow. My reasonong for this goes like this: boxes/irds with similar HD mpeg2/mpeg4 accelerator chip use mere, beggarish 128...256 MB of RAM (DN 211/922, SonicView 8K or something), with that RAM mostly consumed by extended EPG and recording or time-shifting up to 2 HD streams. In other words, hardware acceleration of mpeg2/mpeg4 streams never needs anything more than 64 MB of RAM, it's just because its decoding is accelerated to an extent it's almost real-time. Even when some extra memory is needed for cacheing of frame/format/channel switches, it's freaking superfast 256 MB GDDR4 my 2600 XT can offer.
Alas, it's only available when hardware acceleration working full blast.
Looks like AVIVO mpeg4 decoder developers deliberately stay away from local (PAFF, not MBAFF like in Europe) H.264/AVC specs for DN TS HD streams, or I don't know a registry tweak for turning the hardware accelerator on specifically for such flavour of input. Soundman in this discussion sounded pretty much European, I wonder what are his successes with hardware acceleration for MBAFF DVB-S2 streams? Hey Soundman from overseas, what's your ATi drivers version(s)/betas/tweaks that were successful?
DVBN site is dead for 5 days already, drat! Where all the DVB gurus go, I wonder? Genpix was insulted here, many times, and for absolutely nothing. So, who would advise me on VLC (or better MPC) tuning for playing mpeg4 streams, and specifically how make them use not that creepy opensource internal x.264 or whatever codecs but hardware accelerated streams?

If you want to use VLC you can always stream the data to it. I noticed that using VLC in this way made for a much better picture than the codecs I was using (on STD channels). The only problem is the CPU overhead, which typically adds 10-15% on my system. I just set the streaming to 127.0.0.1 and launched VLC (you have to go to 'Navigation' to find the stream - I still have some issues with finding the right SID there sometimes)
If you just care about the picture quality it may be worth a try. I was able to follow the instructions in the streaming thread above this one and got it to work.
As for the h.264, yah... I was reading the ATI site and found all sorts of known problems. I am not stressing all that much because it works. At the same time, I have not tried connecting to a HDTV unit... my HD is displayed in 1280x1024... (Will get 1920x1200 24" wide screen soon).
The HD Set will have to wait till they get much better and cheaper.
(Anyway, I don't know if I am helping you... you seem to have a better grasp of most things than I do)
